Rounds not being synced to Garmin Connect on iPhone

I have the same issue on my Approach S60 as reported also in the S20-thread. Last 4 rounds not being synced over to mobile. All functions during the rounds seems to have worked as expected, including shot detection, scoring, "save" after the rounds et al. Then - nothing ... 
Interestingly though, number of steps are being synced.  

Have tried to sync also directly linked to Mac. Sync is reported as working but no rounds or stats are transferred over.
