Hi there! I understand you're experiencing an issue where Qobuz is only playing about 20 seconds of a song preview and then skipping to the next track. Let's see if we can get you back to enjoying your music fully.

To start, can you confirm whether you have an active and fully paid Qobuz subscription? Sometimes if the app thinks your subscription isn't validated, it might restrict playback to previews only.

If your subscription is in order, here are some steps we can try on your Android 10 device with WebKit browser:

1. Log Out and Log Back In:
- Log out of your Qobuz account.
- Close the app/browser completely.
- Reopen it and log back in.
This can refresh your subscription status and fix temporary glitches.

2. Clear Cache and Data (if using app):
- Go to your device Settings > Apps > Qobuz.
- Tap on Storage and select "Clear cache" and then "Clear data."
- Restart the app and log back in.
This helps if cached files are causing corrupted playback.

3. Check Network Connection:
- Ensure you have a stable internet connection. Unstable connections can cause streaming issues.
- Try switching between Wi-Fi and mobile data to test.

4. Update the Qobuz app or Browser:
- If using the Qobuz app, make sure it’s updated to the latest version.
- If using a browser, make sure WebKit is up to date.
Outdated software can cause playback problems.

5. Test Playback on Another Device or Browser:
- This helps determine if the problem is device-specific.
- If playback works elsewhere, the issue is likely device-related.

If after these steps the problem persists, it could relate to a temporary issue with your account's subscription validation or with the service's streaming permissions. In rare cases, Qobuz may limit playback to samples if the system thinks there is a payment or authorization issue2.

Could you please try these steps and let me know the results? That way, I can assist you further or help escalate the issue if needed.
