I have iPhone SE. acrobat reader has become so slow I consider it non functional I have to wait and wait and wait for the app to open, I have to wait and wait and wait again for a document I select to open. Then I have to wait and wait and wait for its image/text to actually appear on the screen. Then I have to wait and wait and wait for it to be usable - allow scrolling, allow finger gestures, allow text selection. today, I was looking for some info and going between apps and reader was exiting my document instead of leaving it on the screen so I had to do this over and over again. WTF!!??! I've tried to get assistance and none to be found. Am I the only person having issues? Should I trash reader permanently for another reader? I use it quite a bit and it used to be great. I don't have the same issue on other devices, just my iPhone. However, I have been playing around with other readers to find one that doesn't make permanent choices about the real estate
