Hi! I understand you want to update your height and weight settings in the M2 Wear app and ensure the app accepts those changes.

To help you better, could you tell me if you're trying to update this information on the smartwatch itself or through the M2 Wear app on your Windows device? Also, are you encountering any error messages when trying to save the changes?

Meanwhile, here’s a general way to update height and weight in the M2 Wear app:

1. Open the M2 Wear app on your device.
2. Navigate to the “Profile” or “Settings” section—this is where personal data like height and weight is usually stored.
3. Look for options labeled “Height” and “Weight,” then tap on each to enter your new values.
4. After entering the correct height and weight, make sure to save or confirm the changes.
5. Some versions of the app require syncing with the watch afterward. So, if you have the watch connected, sync your device to push the updated data.

If the app doesn’t accept your changes:
- Check if the values entered are within the allowed range or format.
- Make sure the app is fully updated.
- Try restarting the app or your device and then attempt the changes again.

If you can provide more details about where exactly the process fails or what device you’re using to update, I can guide you through more precise steps!

App says new settings are saved but when I return to personal settings the ne settings are not there

Thanks for the additional info! So, the app says the new height and weight settings are saved, but when you revisit the personal settings page, the changes aren't reflected. Let's troubleshoot that step-by-step:

1. Check Sync Connection:
- Make sure your watch and device are properly connected via Bluetooth. Sometimes, the app saves locally but doesn't sync with the watch.
- Try syncing manually if there's a sync or refresh button.

2. App Permissions and Updates:
- Check that the M2 Wear app has all necessary permissions enabled on your device, especially for storage and Bluetooth.
- Ensure the app is updated to the latest version from the app store.

3. Restart Devices:
- Close the app completely and restart your device. Then reopen the app and try changing the settings again.
- Restart your smartwatch if applicable.

4. Clear Cache (Windows Device):
- Since you are on Windows 10, try clearing the app cache or reinstalling the app to remove any corrupted temporary files that may prevent saving data correctly.

5. Input Format or Limits:
- Sometimes, the app could reject values due to format or limits silently. Double-check the height and weight values you entered fit standard input (e.g., no extra spaces, appropriate units).

6. Try on Another Device:
- If possible, try installing the M2 Wear app on a smartphone and make the adjustments there to see if the issue persists.

If after these steps the problem continues, it might be a known app bug. Some users have reported that toggling several settings on and off or trying alternative settings first can help commit changes in the app8.

Would you like me to guide you through any of these steps in detail? Also, do you primarily use the M2 Wear app on your Windows device or another device like a smartphone?
