@TeamYouTube I can't unsubscribe from a channel and their content has turn bad. I can unsub on PC but it doesn't apply to my phone, uninstalling and reinstalling hasn't worked, logging out and logging back in hasn't worked either. It says an error occurs everytime I try to unsub.
We'd like to look into it. Could you try clearing your browser's cache/cookies and checking it on Incognito mode? Also, try checking it on a different browser to see if that makes a difference. Let us know.
