I just got a new ipad (128 GB, 10.2 inch)-- this is my first ios device since my retina ipad-- which should never have been updated to ios9... My ipad seems to be dawdling at the "it may take a few minutes to set up your apple ID" screen.
If you have not seen progress in those three hours that your posts seem apart, there is something wrong. Being stuck at a screen is not supposed to happen in my opinion.
