Hi Russ,
I did try to copy the features over to another android device, but it was way beyond my technical abilities so I gave up. In the end I manually input all of the attributes that I collected in the field to the layers on the ArcGIS online layers. I then removed the map and all of the features and re-downloaded it. It is now working fine, and I can add and delete features offline and sync them back to AGISOL using the same map, features, and android device as before. I'm really not sure what happened still, I am just hoping that it doesn't happen again.
Thanks for all of the help,
Faye
