Hi there! I see you're having trouble with Stark VPN not working on your Android device after an update. I'd love to help get that sorted out for you. To better assist you, could you tell me if the app is not connecting at all, showing any error messages, or disconnecting unexpectedly? Also, have you already tried any fixes like restarting the app or your phone?

In the meantime, here are some steps you can try to troubleshoot the issue:

1. Restart the app and your device: Sometimes a simple reboot can clear up temporary glitches.

2. Update Stark VPN: Check the Google Play Store to make sure you have the latest version; app updates often include fixes for compatibility with newer Android versions.

3. Clear the app cache and data:
- Go to Settings > Apps > Stark VPN,
- Tap Storage, then select Clear Cache and Clear Data,
- Reopen the app and try connecting again.

4. Check your internet connection: Make sure your internet is stable without the VPN.

5. Verify app permissions: Ensure Stark VPN has the necessary permissions like access to network and background data.

6. Switch VPN servers or protocols in the app settings if available.

If these steps don’t resolve the issue, there might be a compatibility update pending for your Android version or a temporary server problem. I can also check some recent user reports or official channels for any known issues.

Could you share your exact Android model and the Stark VPN version you have installed? That will help me provide more tailored advice.

Are you okay with trying these steps first?
