I have App updates. Go to the Updates screen, tap the "Update" rectangle. The circle appears, sometimes for a split second, other times for a longer period of time, then it reverts back to "Update". Over and over again. Usually after hitting it like 20 times, I can get it to "stick" and actually start updating. It's driving me NUTS. Happens with both my iPad Air 2 and my iPhone 7 Plus. It started happening with my 6s Plus, so it's not the phone itself that's the problem. I've force quit the App Store app, restarted the phone and iPad, tried WiFi on, WiFi off, home WiFi, work WiFi, etc. Nothing seems to help. Anyone else having this issue?
