iPad 8 stuck on set up Apple ID
Just purchased 3 identical iPad 8 and setup a new Apple ID.
All three are stuck at "It may take a few minutes to set up your Apple ID..." but I have left them overnight - still stuck.
Definitely connected to WiFi with Internet. I have tried the suggestion of pressing power and volume buttons to restart.
Also, have turned off, left for 5 minutes and turned back on.
I have checked the new Apple ID and can log in and details are correct.
HELP!
iPad, iPadOS 14
