Troubleshooting Apple Watch Syncing Issues
There are situations where Apple Health passive reading is stopped (ie, syncing is paused) and requires the app to be relaunched. These situations include:
- When the user explicitly kills the host app by swiping up on it from the mutitasking view.
- When the OS kills the app due to low memory, low battery, etc.
- When the device is rebooted.
The user must restart the host app to resume passive reading of Apple Health data.
