Thank you for your quick response. IOS is 10.3.3, I did the most recent update after I had already started experiencing touble with AA. AA version is 17.07.25 I believe I have the original iPad Air. I see the "unexpectedly quit" dialogue box a few seconds after I open AA. The last PDF I was looking at shows up and then the screen goes black and I get the dialogue box.
