I have an iPhone and have the max number of accounts (10) - I want to delete 3 of these, as they are friends that have used my phone previously but no longer play.
When I try to add another account, it tells me:
"You're signed in to the maximum number of accounts. To use another account, sign out of all Google Accounts on this device."
Since no one is signed in to these accounts, it seems like they are already "signed out" but that doesn't seem to be the case. I have tried numerous things and can't figure out how to get these other accounts disconnected from my device.
