You Tube to Chromecast crashing constantly with Pixel 3XL. I do have to reboot the Chromecast to regain functionality, and sometimes also have to force stop the app, clear the cache, reboot the phone and then if all else fails remove all saved data in the youtube app and sign back in. Sometimes it dies when the phone screen shuts off, other times it just stops casting when I open another app while casting. The most common is when I assume it's time to play a commercial and can't for some reason.
