How to set up to receive App notifications
1. Turn off the watch's DND mode and turn off airplane mode.
2. Open the Amazfit app > Profile > Amazfit GTS > App alerts on the mobile phone, tap the toggle to enable "Notification Push"
3. If you're using an Android device, you need to include Amazfit APP into the white list or self-starting list of the mobile phone in background settings and keep the app running in the background to protect it from being detected and killed by the mobile phone's background processes, which could disconnect the watch from the app, and consequently no app reminder will be received.
