Question: Can I undo the recent update???
Aside from the issues that can along with the original update, requiring 11.1.1...I like just about NOTHING with this update. No Airdrop option on the command center; WiFi; Bluetooth and cellular are all screwy now (automatically turning back on when I need them off- out of the US); my screen gets stuck in the half down mode a lot; apps are freezing at least once a day....so ya, this update is not good. For me at least. Can I go back to the previous iOS??
