Thanks for your reports about YouTube, YouTube TV and YouTube Music access issues. We're working on resolving this and will let you know once fixed. We apologize for any inconvenience this may cause and will keep you updated.
Do you realize how many people just force stopped, cleared cache, uninstalled, restarted their phone, and very possibly threw phone against wall? I think this is YouTube's way of saying, y'all are addicted and need some help.
