How do I force an attribute to sync from iOS?
Sometimes you might need to force a particular attribute to sync. For example, if you had some incorrect data in Apple Health from a couple of weeks ago that you've since deleted or edited. Force syncing allows you to sync data from the past 30 days for one attribute at a time.
To force sync an attribute, open the menu in Exist for iOS and tap "Apple Health settings". At the bottom of this screen, tap "Get help", then tap "Force sync" at the bottom of the next help screen. Tap an attribute on the force sync screen to start a 30-day sync. While the sync is in progress, other attributes cannot be forced to sync.
