ipad setup using iPhone

I bought a new iPad Air 5th Gen. When I try to setup the iPad using my iPhone 13 it seems to transfer everything perfectly. But after the download is complete I suddenly get a message in Settings saying Restore in Progress. "An estimated 100 MB will be downloaded to finish restoring your apps and data." This download never completes even after several days. The iPad works fine, but I can't install any software updates until the "restore is complete" which never happens. I had the same issue with an older iPad 6th Gen I bought a few months ago. The download never completes. Obviously there is an issue here with the setup and not the devices themselves.

Just to note I've tried resetting the iPads and doing the setup again. Same results with both devices. I also spend an hour on chat with an Apple rep who had me redo all the solutions I had already tried, but he couldn't figure out the problem.
