Diagnosis
Smart Guide data sync failure. The app is not receiving session data from the handle post-brush.
How to Fix It
Ensure the brush is paired before starting. The session logs only transfer after brushing, when the app is open and in the foreground on your phone. Keep the app open and near the brush for 30 seconds after you finish.
If That Didn't Work
Check app permissions. The Quip app requires Bluetooth and Background App Refresh to be enabled. On iOS, ensure 'Precise Location' is allowed. On Android, allow location permission for Bluetooth scanning.
Heads Up
Data sync is one-way, from handle to phone. If you close the app before the sync completes, that session's data is lost. The handle's memory only holds the most recent session.
