Q: Encrypted PDF will not open after IOS 10 update
Ever since updating to IOS 10 I cannot open password protected PDFs on iPhone. When I click on pdf a gray screen opens with the PDF file size. There is no place to enter password. The screen locks up and I have to completely close the mail. This problem only started after update. Phones not updated do not have a problem. Several coworkers are using newer phones with the same problem. Our IT department says it is a problem with Apple.
IF I choose another app to open the PDF a message says the file cannot be open or is corrupted. Even using a website for mail will not permit the password protected file to open. Has anyone else had this problem or have a solution?
iPhone 5, iOS 10.0.2

Our users at work are reporting this too. Our paystubs are sent as encrypted PDFs to their work email and all the symptoms you describe above occur on all iOS devices that have been upgraded to >10.0.0. I applied the 10.0.2 update hoping it was fixed, but still nothing. Saving to iCloud Drive also is not effective.
The only workaround I've found is to open in Dropbox or Google Drive. Those apps' built-in pdf viewer opens the file successfully.
