Activation lock issue.
My apple iPad won’t let me access my iPad as I have an activation lock warning come up tell me to sign into my Apple ID, however I’m not 100% sure what my old Apple ID is as it was a quite a few years back I set up my iPad for college use. So now my issue is I’m locked out of my iPad and can’t access it at all without this forgotten Apple ID. Any help on this matter would be appreciated.
