Apps stuck on "Loading..."

My wife has been using an older iPad Pro 10.5”. She just got an iPad (standard) 8th generation. The transfer of the new iPad from the old one seems to have worked. All the apps that were on the old one are on the new one, but they’re all “Loading...” They all progressed to a little more than half way, based on the little shaded progress circle that appears on each app’s icon. But they all stopped there. None of them have progressed past that point. I have turned the new iPad off and on, and even tried a hard reset. Is it common for the progress to just stop at certain points?
