It looks like you are running into a known issue we have in 6.1.2 where some or all attachments will not get displayed. The good news is, we have already worked through the issue with a couple of other customers, and the problem should be fixed after 6.1.3 is published to the App Store. We plan to do that either today or over the weekend.
After 6.1.3 is installed on your device, you should be able to see all of your attachments again. If you still see an issue after 6.1.3 is installed, please let us know immediately so we can figure out what's going wrong.
