[AC Question]

I used to be able to open the attachments to my Emails but am now unable to open or download them. I think this is since I have upgraded the tablet to Android 5.1

If you can't open them after they're downloaded, it depends on the file type of the attachment - you have to have an app that can open that file type (the email app only opens emails, it doesn't open files).

If you can't download them, contact your email provider or try a different email app.
