A. 1. Ensure that your watch is fully charged and connected to the app. 2. Restart both the watch and the smartphone. 3. Open the Suunto app and navigate to the 'Dives' section. 4. Manually refresh the sync by pulling down on the screen. 5. If dives still do not sync, try resetting the Bluetooth connection by forgetting the device in your phone's Bluetooth settings and re-pairing it.
B. 1. Check for any available updates for both the Suunto app and your watch firmware. 2. If updates are available, install them and attempt to sync again. 3. If the issue persists, consider exporting dives manually from the watch to a file and then importing them into the app.
