I'm a teacher in the UK and have 30 kids in my class.We have bought 35 (older) Nexus 7 tablets.
I have one Google account which I want to use across all devices so that the young children don't have to remember user names and passwords.
The trouble that I'm having is that not all of them are able to be logged in at once. There appears to be a limit as to how many devices can be online with this account at once. We're doing this to be able to use Google Drive so that the kids can produce work and save it into Drive.
We are finding that as tablets are booted up, already online device are logged out from Google and I have to log them in the android backend.
I'd love to get this sorted. It's for the kids!
