Hi! I see you're having trouble with the favorites list not working in the Tango app on your Windows device. I'd love to help you get that sorted out.

To start, could you tell me a bit more about what's happening? For example:
- Is the favorites list not showing at all, or are some items missing?
- Have you recently updated the app or your device?
- Are you logged into the app with your usual account?
- Have you tried restarting the app or your device already?

Meanwhile, here’s a general step-by-step way to troubleshoot this issue in the Tango app:

1. Restart the App: Close the Tango app completely and reopen it. Sometimes, minor glitches clear up this way.

2. Check for Updates: Make sure you are running the latest version of the Tango app. Often, fixes for issues like the favorites list are in updates. You can check the Windows store or the app’s official site for version 4.0 or newer.

3. Log Out and Back In: Sometimes, account syncing issues cause favorites not to appear correctly. Try logging out of your account and logging back in.

4. Check App Permissions: Ensure Tango has the necessary permissions to save data locally. You can check this in Windows Settings under 'Apps' -> 'Tango' -> 'Permissions.'

5. Export Favorites (if possible): If you can access the favorites temporarily or on another device, export or share your favorites list as a backup (some versions allow this). Then reinstall the app to refresh the data.

6. Reinstall the App: If the above don’t help, uninstall and reinstall Tango on your device. This can fix corrupted app files.

If these steps don't resolve the issue, you could try updating to version 4.0 as some users reported fixes regarding lost favorites in that update1.

Would you like me to guide you through any of these steps? Or did you already try some of them? Let me know so I can assist you better!
