@YouTube I keep getting an "oops, something went wrong, There was an issue signing you into YouTube. Troubleshoot here." message when I try to log in with my google account.
Is this happening on a PC or on Mobile? If you're using mobile, make sure that you have the latest version of the app by reinstalling it. Clearing the cache and cookies also helps fix these issues too. Instructions here: https://yt.be/help/Cko1 . Let us know if that works!
