Chromecast functionality

@Rubion

I use a Motorola G 2014 fully updated and experience the same error.
Looks like a problem with some devices only because others can use it nicely.
I gave up on this since I only use it at home with another phone (Lineage OS on a Samsung SIII).
If you will, you can get a log from your phone (check how here) and submit it to the /e/ team via Gitlab (this matter is being treated here).
