Hi there! I understand you're stuck on the loading screen with the BIMOBIMO app and can't log in, even though your VPN is active. Let's try to get this sorted out together.

First, just to clarify:
- Are you using the latest version of the BIMOBIMO app on your Android 15 device?
- Have you tried connecting without the VPN, or switching VPN servers?
- Is your internet connection stable?

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

1. Restart the app: Close BIMOBIMO fully (swipe it away from recent apps) and reopen it.
2. Check your internet: Try turning off Wi-Fi and use mobile data, or vice versa, to see if the connection improves.
3. Disable VPN temporarily: Since you mentioned VPN is enabled, see if the app loads without VPN active. Sometimes VPNs interfere with app communication.
4. Clear app cache: Go to Settings > Apps > BIMOBIMO > Storage > Clear Cache. This removes temporary files that might cause loading issues.
5. Update the app: Make sure your app version is the latest from the Play Store.
6. Reinstall the app: If the above don't work, uninstall and reinstall BIMOBIMO.

If the issue persists after these steps, let me know. We might need to check for any known server issues or advanced network settings.

Does that help? Are you comfortable trying these?
