Finally got 10.2.2 installed - created a very simple feature class with attachments - globalid, archiving and globalid migrate relationship attachments. Published Feature Service enabling editing and sync.
Registered on arcgis.com with remember password - it is a secure feature service.
Allows offline on arcgis.com.
Works OK online.
Go to download offline in Collector and it gives me the message InvalidURL. Any Ideas?
Have shared in our debugshare group with mobileios.
[EDIT] Republished service in directory with no security and it works!! Not good.[EDIT]
