@suzzlo That is correct. The sync wont show and also the sync is non-blocking.
In future update this icon will appear (not sure if on the one to come next but it should be soonish)
Also note that the moves are not marked as synced.
That is because we dont want to loose any data during beta.
You can easily use Suuntolink or another phone with movescount to sync the moves to movescount etc.
