Follow this workflow, I bet sync with attachment will work.
1. create new SDE geodatabase, feat. dataset and feat. class
2. add globalIDs
3. enabled archiving
4. enable attachments
5. publish service with sync enabled
6. add feat. service as item in Arcgis.com, DO NOT store credentials with the item if service is secured. BUG-000084538 was logged yesterday. Support helped me to determine storing credentials with secured services when added to arcgis.com was causing issues with collector.
7. create webmap with your newly added item
8. share both service and webmap
9. take offline with collector, create points, take photos with camera
11. this workflow works every time, no issues. Key items: NO versioning, NO storing credentials .
