I am using acrobat reader in my nexus 5x (Marshmallow) whenever I try to open a PDF link on any website it asks me for the screen overlay permission. But this app is not listed in screen draw over settings therefore I can't activate the settings. Besides in my app permission menu storage permission is not active for the acrobat reader and when I tried to activate it ask me to first deactivate the screen draw over setting which is not possible .Because of all this fuss I am unable to download any PDF file from any site.
Thanks for reporting the issue. Could you please confirm that you are observing the issue on opening a file from any hyperlink? If you are unable to open any file, could you please restart the phone and let us know if you still observe the issue?

Yes I am observing this issue with all the hyperlinks and even after
restarting my phone nothing has changed.
May I know the version of Acrobat? Also try to clear Acrobat cache and then try it.
