Finally I was able to use my stock Bluetooth keyboard after upgrading to iOS 11.2.5. Now the problem is: while the keyboard is connected to the iPad and I can use Home key, from time to time, I can’t type with the keyboard. I went to the Apple store and was told to restart the iPad and try to connect the keyboard again. It works, after a few iterations but I am really unhappy with it. I have been using computer since later 1970s and this is the the FIRST time I ever had keyboard issues! Seriously?! Apple? Does anybody has the same problem? Any suggestions???
