I am running iOS 12.4.1 on an iPhone 7Plus with Adobe Acrobat App version 19.07.00 (20190719.193727). I have attempted to delete and reinstall the app with no success.
All of my files now only display in inverted black & white. There are no colors. This appeared a few versions ago. I’ve been hoping that updating my OS and the app would resolve the issue but to no avail. I have reviewed all possible settings and nothing pops out. This just started happening one day.
