Hi there! I understand that you're able to use your code to control Cove on the panel itself, but when you try the same code on your phone app, it gets rejected. Let’s figure this out together.

First, a few quick questions to narrow things down:
- Are you using the latest version of the Cove app on your phone?
- Has this issue just started recently, or has the code never worked on the app?
- Have you tried restarting your phone app or reinstalling it?

Here’s a simple step-by-step list to try:

1. Restart the Cove app on your phone: Close it completely and open it again to refresh the session.
2. Check for app updates: Go to your app store and make sure your Cove app is up to date.
3. Re-enter your panel code carefully: Sometimes minor entry errors can cause rejection on the app.
4. Restart the panel: Sometimes the panel can have communication glitches. Try unplugging it, then holding the “Home” and “Call” buttons simultaneously for about 12 seconds to reboot1.
5. Reinstall the app: Uninstall and reinstall the app to rule out any corrupted files or cached errors.

The fact that your code works on the panel but not the app might be related to app authentication or syncing issues. If none of the above helps, you might want to verify that the app is correctly linked to your panel and account. Sometimes, app authentication tokens can expire and may require you to log out and log back in or even remove and re-add your device in the app settings.

Let me know what you’ve tried so far or if you want me to walk you through any of these steps! Are you satisfied with the guidance so far?
