Reader keep crashing with the latest update

Hey all,

First of all, thanks for fixing a few bugs with the latest update; first launch error and not remembering the recently viewed page.

However, with the new patch it seems like other bugs have occurred

Problem: Adobe Acrobat Reader crashes whenever I do 'anything else'. Meaning, if I turn off my iPad and turn it on, it's back to Reader but the screen is frozen, then crashes so I have to restart the program. Same thing happens when I swap the screen to something like web browser or music player and come back to Adobe Reader. The screen is frozen, then crashes a few seconds later, so I have to start the program again.

iOS version: 11.2.1

Adobe Reader version: 17.12.15

Thanks!
