Adobe released an update for Adobe Acrobat Reader for iOS, version 16.01.05. It fixes a bug that was causing users to be logged off of the Adobe Document Cloud “unexpectedly”, along with some other stability improvements.  This version also improved their palm rejection feature that fixes problems when you rest your palm on the glass of an iPad Pro while using Apple Pencil. Look for an update with a 3/30  date in the App Store.
