Hi there! Thanks for reaching out. To help you better, could you clarify what exactly happens when you try to change the dial library? For example, do you see an error message, does the app freeze, or does it just not update the watch face? Are you trying this from the FitCloudPro app on your Android device?

In the meantime, here’s a common approach to resolve dial library issues on FitCloudPro:

1. Restart both your smartwatch and your Android phone: Power them off completely, wait about 30 seconds, then turn them back on. This can often clear temporary glitches.
2. Ensure the FitCloudPro app is updated: Go to Google Play Store and check if there’s an update available for the app.
3. Close and reopen the app: Sometimes restarting the app can refresh the dial library.
4. Check the Bluetooth connection: Make sure your watch is properly connected via Bluetooth to your phone.
5. Try clearing the app cache: Go to your phone’s Settings > Apps > FitCloudPro > Storage > Clear Cache.

If after these steps, you still can’t change the dial library, could you tell me which FitCloudPro app version you have and your smartwatch model? That way, I can guide you more specifically or look into any known issues for that configuration.

Does this sound good so far? Let me know what you’ve tried or what you observe when attempting to change the dial library!
