I have a website that has a password protected area containing a number of PDF files (which individually are NOT password protected).
From a Android phone and tablet using Adobe Reader (for which there are no outstanding updates) I get "Error cannot open the file" once I can see the file (having entered the password protected area of the website). If I request "Open in a new tab" the file downloads and opens correctly. All files open via a windows PC.
PDF files in a non password protected area on the same website open without any problems.
Colleagues on different Android devices have the same problem.
Any ideas ?
May I know the version of Android you are using and the device? Also what is the version Adobe Acrobat Reader?
You are correct. It seems to be a bug with Adobe Acrobat Reader 15.2.1. I am able to replicate the issue at my end also. I have tested this on Android 5.1.1 device.
Glad it's not just me !
I'm also using Reader 15.2.1 with Android 5.1.1.
