I had the same issue when I initially synced from the demo server: I could not see current teas or the tea types in the survey form.
I tried syncing again, and noticed there was an error and the sync did not complete.
However, the tea types were now available in Survey.
Since then I’ve done some sync testing and have not been able to successfully complete a sync from the demo server. It seems as though one of the demo apps, Geotagger, has a large number of files attachments and that the sync is timing out (that’s my observation, not confirmed).
There is an update to the demo server going on at the moment, and when the new server has been set up the sync issues should be resolved by cleaning up the data on the demo apps.
I’ll update this thread when that’s been done.
