The Zepp app does not show a pre-populated list of existing apps on the mobile device. Only apps that have generated notifications will appear in the list, and it will populate over time as and when notifications arrive.
The troubleshooting process steps are as follows:
A. Enable App Alerts in the app.
Note: If you enable Receive App Alerts Only When Screen Off, you will only receive app alerts when your phone screen turns off.
B. Ensure the phone's Bluetooth is enabled.
C. Check whether the watch is in Do Not Disturb mode (DND mode). If the watch is in DND mode, please disable the mode.
D. Make sure the phone's notification bar is working properly.
F. Go to the mobile phone system settings, find the App Notifications feature, turn it off and then back on, restart the phone, open the Zepp app, and try again.
G. Open the Zepp app and go to Devices > Amazfit Bip 6 . Tap Run in the Background to check the settings and make sure the Zepp app is running in the background.
If you are using an iPhone, go to Settings > Notifications > Zepp App > Enable All Alerts. Please make sure you have turned on the Other toggle in the Zepp app.
