Similarly, I cannot log into my YouTube account on some devices. I can log in to my Google account, but it doesn't have the same subscriptions, likes, watch history, etc. On other devices, if I log in with my Google account it logs into my YouYube account, which has what I need. The two accounts must have been synced at some point, but I can't always access the original YT account, which sucks.
