I am curious if anyone has tried using this new functionality yet? I am able to "synchronize" with smaller feature services (less than 200 features, few domains, simple tables), but when I attempt to synchronize a larger feature service (1000's of features, large domains, several related tables, the screen just hangs at "Generating Token". Even with this larger feature service, I have zoomed into an area that only has, perhaps 50 features in it - and still get this behavior.
I am connecting to a secured feature service hosted on an Amazon EC2/ArcGIS Server 10.1 SP1 instance with a Trimble Nomad.
