I recently updated my iPad air to the iOS 7.1 beta 2, then updated to beta 3. I later noticed the keyboard in pages was acting quite strange. So, I restored my ipad back to beta 2 and restored from iCloud as well. The keyboard still is acting strange. It's extremely slow and the backspace button barely works. It will not let you long press. I'm not sure if this is a beta issue or just some other problem. It could have been doing it before the 7.1 beta update because I hadn't been using it. It isn't doing it in any other app. Also, I tried turning off iCloud documents and data but that didn't work either. Any suggestions? Known issue?
