I have been able to make the installation work and initial sync work.
Issue is - New messages are not synching to the device.

If I login as the testuser to the webadmin and change some settings, It triggers the sync and messages sync upto that point. Any new messages after that still do not sync.

Goint to https://mobilityserver tells me:

Event Errors Waiting to Sync to Device = 0
Converted Events Syncing to Device = 3
Pending Events From Device = 0
Device Events Sent to Sync Engine = 0
Items Synced to Device = 1775

Any Ideas !!!
