My main complaint is when it decides to just stop casting to Chromecast in the middle of episodes randomly - then I have to open the app, reconnect, and resume.
Also I find the Chromecast controls stop responding frequently making it so I can’t pause what I’m watching - it’ll like disconnect from the Chromecast but keep playing.
My partner also complains about lots of bugs on the iOS app.
I’ve been having trouble with this too.
So far my best assessment is that the problem stems from the Chromecast not playing well with my router. Resetting the Wi-Fi on my router tends to fix the problem, but it’s seriously annoying.
Separately, I also have issues with the play/pause not working when casting and some other weird interface behaviors sometimes. But all in all, it’s worth complaining, but it still works better than everything else.
