New iPad stuck on spinning screen during set up

If your iPad is not operating as expected, try a forced-restart of your iPad - as this will often clear an isolated software issue:

Force restart iPad (models with Face ID or with Touch ID in the top button)

If your iPad doesn’t have the Home button, do the following:

1. Press and quickly release the volume button nearest to the top button.
2. Press and quickly release the volume button farthest from the top button.
3. Press and hold the top button.
4. When the Apple logo appears, release the top button.

Have you successfully connected to a Wi-Fi network? Is the network free of VPN, anti-virus, or any other exclusionary product? It should be.
