Chromecast Issues - LG G5 Questions & Answers

Is it just me or is there a problem with LG G5 (H860) connecting to Chromecast?
I can't get to connect to my 2 chromecast devices on my TV using my new LG G5 (H860) cellphone. Also tried Localcast and YouTube. It still won't connect.
My other devices work alright (Samsung Tab A) connecting to the chromecast device. I've also tried a different chromecast unit and it still won't connect
See screenshots for reference.

Well.. I have a fully working screen casting.
One with the older model Chromecast and one with the new model.
Just used one of them today and earlier this week the other..
Tried to reboot your device and chromecast?
Edit.

I have the LG G5 LS992 (Sprint-US variant) and CHromecast works just fine. I tried Youtube, Netflix and Spotify with no problem.

You are not alone in this problem. I too have the LG G5 and have begun noticing connection issues with this specific handset.
I can usually get it to connect without issue and begin the streaming process, then somewhere along the line, the phone disconnects on it's end of things while the media continues playing on my home theater or my TV and I then have zero control over what's playing.
I'll also see intermittent flashes of the cast button on my phone's screen and when I go to connect, it asks for the CC's pin. Problem is, once something's streaming, you can't see the pin, so I have to unplug any and all power to the CC to get it back to working order. I have one in my living room and one in my bedroom and both will disconnect at various times from the phone, but not the wifi network. I know it's the phone because my old HTC One M8 will remain connected, without issue. Our tablets and PCs remain connected as well.
It's only this phone that I'm having trouble with. Even the Google Cast app doesn't find the CCs in the house, just that it knows I have backdrop settings for both.
It's become a major annoyance since we stream most of our entertainment now. I don't know why it's doing it, but I'm hoping someone has an idea. I do, but it may be nothing of value....
In Marshmallow, there's supposedly a setting to allow the wifi to sorta "sleep" to save on battery power until you touch the screen. I'm wondering if the wifi goes to sleep and disconnects from the Chromecast, causing this issue? If that's the case, is there a way to disable that so it doesn't do it? I have to charge the battery or swap it out on a regular basis anyway, so I can't imagine I'm saving much by leaving such a feature activated.
