All of a sudden today my iPad stopped syncing iMessages. I turned iMessage and Facetime on and off, and reset my device, several times but nothing worked. So I signed out of iCloud, reset my device, then tried to login again to iCloud. The Settings screen has been stuck at "Verifying" for 15 minutes, and I have repeated this process a few times with the same ending. While it's "Verifying" the Settings screen is frozen. I can't scroll or tap anywhere, but screen rotation still works and I can go to the App gallery and all apps work fine. FYI my internet is working just fine as I am writing this post, and I can also login through icloud.com just fine. Note I have 2-step verification on. Thank you.
