YouTube TV has stopped working in Opera beta — the homepage loads if logged out, but logging in takes you to a blank page at tv.youtube.com
I've done all the troubleshooting (updating, reinstalling, etc.), didn't help.
YouTube TV works fine in regular Opera, though. Just a beta problem as far as I can tell (I haven't tried in Opera dev, though).
Browser: Opera beta
System: Mac OS X 10.15.3 64-bit
