Logging out of Apple ID before resetting iPad Air 1

[Alwyn]

After I had reset the iPad, using the erase everything otion,I realised that I hadn't logged out of my Apple ID so I started to set it up and, when I got to the Apple ID login, I got a message to say the the iOS was too old to allow this. In setting up its replacement an iPad Air 2, I removed all the previous iPads, so It is possible that this is the reason.

If it isn't the reason I need to be sure that a buyer won't have this problem.

If it isn't the reason

It is the reason: More recent iDevices have this capacity (as do recent macOSs) which allows you to see what products are listed within your Apple ID - and the chance to disassociate them from your Apple ID.

So once you remove the old iPad from your Apple ID - as you have - job done.

There should be no problems for a new owner.
