iOS 10 major keyboard lag
I upgraded my 4th gen iPad to iOS 10 recently, and I am experiencing major keyboard lag. I can only type one letter at a time then wait 10-20 seconds and it appears on the screen. This is very frustrating as it takes forever to type an email. I have tried many things that have been suggested like turning off cloud sync, reset all settings, doing a hard reset; all of that to no avail. Please help if someone has figured this out.
iPad (4th gen) Wi-Fi, iOS 10.0.2
