Since the new update, password protected documents can not be opened. I get the error message that the file is corrupt. I used this same type file hundreds of times prior to the update with no problem. Please fix. I need to view these documents on my iPhone. Update on May 25, 2017... the problem was resolved for a while but, after the update prior to this one, the problem returned and it continues through this update. I am unable to open password protected documents.
