Hi there! I understand you're having trouble with the HDO Box app where movies aren't playing, and instead, a link is shown for viewing the movies. Let's get to the bottom of this.

Could you tell me a bit more? For example:
- Are you using the HDO Box app or watching through a browser?
- When exactly does the link appear? Is it immediately after selecting a movie?
- Have you tried any fixes so far, like restarting the app or your device?

Meanwhile, here are some common steps that usually help with this issue on Android devices like yours (Android 10, WebKit browser):

1. Restart the App: Force stop the HDO Box app from your device settings, then reopen it to see if the problem persists.

2. Clear Cache and Data: Sometimes the app's cache or temporary files cause glitches.
- Go to Settings > Apps > HDO Box > Storage > Clear Cache.
- If that doesn't help, try “Clear Data” (this will log you out, so be prepared to re-login).

3. Check Internet Connection: Make sure your connection is stable. Sometimes slow or unstable networks cause the app to fail loading the video player and instead show a link.

4. Update the App: Ensure you have the latest version of the HDO Box app installed. Older versions can have bugs causing playback issues.

5. Use VPN or DNS Change: Some users report that geo-restrictions affect playback. Using a reliable VPN (like ExpressVPN or NordVPN) or changing DNS settings (e.g., 1.1.1.1) can help.

6. Reinstall the App: Uninstall HDO Box completely and reinstall it from a trusted source to reset any corrupted files.

If after these, movies still don't play and only links show up, it might be a temporary server or app bug that users have reported recently. In such cases, the developers usually fix it with updates.

Could you try these steps and let me know which ones you've already attempted? That way, I can guide you further if needed.

Are you satisfied with this approach so far?
