Why can't I open any email files on my iPhone.

I used to be able to tap and open but now it just comes up with the file name ever since I did the last download. I have Adobe reader but I can't get it to open anything

It's possible that the app may need to be updated. Try rebooting your device or using another .pdf reader.
