I am going to attempt to replicate this on an android Tablet but essentially this is it:
When a user clicks on the Attachment a popup appears with the following options:
1. Download
2. Open Attachment
In many cases #2 is greyed out and prevents the user from viewing the attachment. I have attempted to add apps to allow files to be viewable but in many cases this doesn't seem to work.
When the user selects #1, it claims the file is downloaded and saved but the file is not findable.
Any thoughts about either of these two options would be appreciated as my Android user is the one experiencing this difficulty.
