No Push Notifications after a while - randomly - Android Q&A, Help & Troubleshooting

Hi..
Im using a Stock Huawei Honor 6 with Emotion UI and my problem is that my incoming push notifications seems to be in a queue until i reconnect my WiFi or 3G. After doing this all notifications come directly.
Where can I start to search the reason? Which services belong to the push service and have to run?
Hopefully you can help

[HELP] Whatsapp and GMail: I don't receive notifications when phone is in deep sleep

Android Nougat 7.1.1
I excluded Whatsapp and GMail from battery optimization (doze), I set the notifications to level 4, ensured that there is no data restriction for these apps; however most of the time to see notifications I have to wake up the phone from deep sleep (by turning on the screen): in facts, most of the time when I wake up the phone, after some seconds I receive a lot of old notifications and missed calls of Whatsapp and also emails of GMail/Inbox.
I also tried by not closing whatsapp, but leaving its window in background, but nothing solved this major issue.
In developer options, under active applications section, whatsapp and GMail are not always present (after a while they falls in "background applications", which, to from what I heard, is ok).
I also heard that to keep an app always active (if we are without root) there is the need to have a persistent notification, but Whatsapp and GMail are not provided with such option.
On another phone with Lollipop 5.0, a phone which I rooted, I had the same issue which I solved by using "Push Notification Fixer", but on the phone with Nougat (an Xperia) I can't/won't enable the root (otherwise I will lost the camera's DRM); since "Push Notification Fixer (PNF)" on the rooted phone was able to solve the issue, I suspect that the culprit is GCM (Google Cloud Messaging)? by using PNF on the rooted phone I set the "heartbeat" to 5 mins.
I know that there's also a "no root" version of PNF, but doesn't works reliable for me.
So: maybe there is a way to always keep Whatsapp and GMail In running apps or there is another workaround/fix?
Thanks.

Well, since yesterday I installed an app called "Recurrent Notification Manager" which is able to intercept notifications from apps which I choosed (Whatsapp and Inbox) and the most notable thing is that this app is provided with a persistent notification: I noticed that when I receive a Whatsapp message, is firstly reported by this app instead of whatsapp. What I mean:
First of all: I inserted whatsapp inside this app by choosing a green color of the led and a personal sound.
1) I send a messagge to myself from another phone after a while of deep sleep (eg 1 hour)
2) I receive a notification after few seconds
3) I wake up the phone and I see a notification from "Recurrent Notification Manager" but nothing from whatsapp itself
4) I open whatsapp and I receive the message.
Well, this behaviour, at least, seems to make me able to immediately receive notifications.
I will keep on do tests and I hope that this app really solved the bothersome issue.

I'm sorry for the noise: I'm updating step by step this thread to notice every single action that seems to help.
In "Recurrent Notification Manager" app, I also set to monitor "ongoing notifications"; these appear to be the notifications that Whatsapp often displays before of receiving a message, when it says "Checking new messages" and "You may have new messages" (I'm not very sure about the English grammar since I have the Italian language set on my phone) : I often see these notifications before receiving a message and sometimes I also have to wait some minutes, to receive a message: "Recurrent Notification Manager" will send me a "real notification" when Whatsapp shows only these "early notifications"; in facts, as I've said, when I receive a new message, the first notification is from the notification manager instead of Whatsapp.

WhatsApp & Gmail notification delay

Dear all,
I'm currently running a stock S9+ on android pie, on the Virgin (VMNP using EE network) in the UK. I experience delays with WhatsApp and push gmail notifications very regularly.
From searching on the internet I have come across two common reasons. One of which suggests this is a Samsung One UI induced issue and a combination of Samsungs implementation of doze not working properly in the android Pie update.
The other reason suggests that Virgin is just a garbage network piggy backing on EE and they are throttling data based notifications for whatever reason?
Does anyone else have similar experiences to this and have you come across any possible solutions?
I have resorted to using Samsung email to solve the push notification problem, I just have it syncing every 15 mins which works perfectly fine and I actually prefer the app to Gmail. Battery impact is negledgable as well.
Any input here will be greatly received so thanks in advance!

Android 11: Change notification settings of immutable notification provider

The problem presents itself as there are some notification providers (e.g. call services) that don't allow the user to disable specific notifications (in this case WiFi Calling).
Since receiving the official Android 11 on my Pixel 4 XL yesterday, there is a permanent notification telling me emergency calls are not working over WiFi Calling (thanks I know, get out of my sight).
Usually, notification providers can be turned off entirely or selected groups of notifications of a service can be turned off. Well, seems like you can't turn this one (or call services at all) off.
Is there anything one can do about this? I don't want to have this notification be there 24/7.
I am very open to hacky solutions, whatever it takes to get rid of unwanted permanent notifications. The optimal solution would be something that allows me to, in general, modify previously immutable notification settings.

WhatsApp notification problems

Hello everyone, I have a Huawei P40 Pro and I only get WhatsApp messages when I open the APP, no matter how long it has been since they were sent to me. I've tried various things and I've written to WhatsApp help, but it seems like a robot that responds the first thing it thinks of, even though it's unrelated to what's happening to me.
For example send this query with information of what you had done:
The messages only arrive when the app is opened, at which point they arrive in a flash. As long as it does not open, no message arrives or notification.
1.- The app's battery management is in manual mode, so it can work in the background
2.- The use of data in the background is allowed
3.- Notifications are allowed and enabled, with sound and vibration
4.- It happens both with the data of the Sim and with the WiFi connections, having adequate coverage working Internet in all the apps at high speed.
5.-The latest version of the app is installed
6.-The mobile is a Huawei P40 Pro WITHOUT Google SERVICES installed
7.-I have tried to uninstall and reinstall the app
8.- The only way to reproduce the error so that you can see it is to record the screen by opening the APP so that you can see how the messages arrive, but it won't show that hours can pass if I don't open it .
And the WhatsApp help service answers me:
Hi, thanks for your message. Your phone uses Google Cloud Messaging (GCM) to receive push notifications on WhatsApp. The most common reason for delayed or missing notifications is a lack of connection between the Wi-Fi network, mobile operator, and GCM. In order to prevent these disconnections from happening, make sure that the phone has a strong Internet connection and that background data is not restricted. For more information, see this article. If you have any other questions or concerns, please do not hesitate to contact us. We will be happy to help you.
As you can see, he answers things that in the question itself I already tell him that I have verified. Could someone help me solve it or at least contact a WhatsApp human who can understand my question?
Same Here. If my Huawei Nova 10 SE has a locked screen whatsapp notification do bit appear. As soon as I wake up the screen the notification popis up. Anyone knows the solution? Although, after some time...5, 10 or 15 minutes something happens and the notificaton pops up.
