I did the IOS upgrade to one of my two iPads (to 9.0.1) -- and now I have far more issues than with IOS 9. So I sure as hell don't want to upgrade the other one, which is now nagging -- even trying to preset a time (!!!) -- to upgrade. Oh, hell no!
Apple, I hate you.
Please do another upgrade to FIX the slews and slews of issues that are making my poor iPad so miserable. That is all, Apple...
