Google Drive Invalid Credentials

Hi, I migrated from Dropbox to Drive backup and since doing so I keep getting random Invalid Credentials emails from sites configured to backup to Drive.

I have a single account setup just for site backups, locked credentials against accounts in the AIO Drive settings.

I’d setup the folder system within a containing folder in Drive so all sites backup to the correct files. But it seems that whenever the credentials issue pops up I have to relink the account and select the folder again.

This is becoming a problem as I have many sites backing up.
