Hi There, thanks for stopping by!

To enable Master Sync, just follow these simple steps:
Pull the status bar from the top of the screen down using your two fingers.
Look for the quick selection icon for SYNC.
Tap the Sync icon and make sure it's enabled (indicated by green color).

Hope this helps!
