Hi! I see you're still not getting the Rumble app program start notifications despite following the previous steps. Let's make sure we cover all bases to get those notifications working correctly on your WebKit device with Android 10.

To start, could you please confirm:
1. Have you checked that notifications for Rumble are enabled specifically in your Android system settings? Sometimes the app might have permissions, but system notification settings could still block them.
2. Is the Rumble app fully updated to the latest version from the Play Store or your source?
3. Have you tried clearing the app cache or reinstalling the app recently?

Assuming these are all okay, here’s a step-by-step to troubleshoot notification issues specifically on Android 10:

1. Verify App Notification Settings:
- Go to Settings > Apps > Rumble.
- Tap Notifications.
- Make sure notifications are allowed and "Program start" or similar notification categories are enabled.

2. Check System Notification Settings:
- Open Settings > Notifications > See all apps (or similar based on your device).
- Scroll to Rumble and ensure notifications are turned on.
- Look for any special rules like "Do Not Disturb" exceptions or battery optimization that might block background notifications.

3. Disable Battery Optimization for Rumble:
- On Android 10, battery optimization can prevent apps from sending notifications properly.
- Go to Settings > Battery > Battery optimization.
- Find Rumble in the list and set it to Not optimized or Allow background activity.

4. Ensure Background Data is Allowed:
- Check Settings > Apps > Rumble > Data usage.
- Confirm “Background data” is enabled, so it can receive notifications when not open.

5. Clear Cache (if not tried already):
- Go to Settings > Apps > Rumble > Storage.
- Tap Clear Cache.
- Avoid clearing data unless you want to log in again.

6. Reinstall the App:
- If it still doesn’t work, uninstall and reinstall the Rumble app which can reset any corrupted notification settings.

If you have already tried some of these, please let me know which ones, and we can dig a little deeper—like checking for any device-wide notification blockers or potential server-side issues.

Also, do you receive any notifications from the app at all, or is it just the program start notifications that are missing? This will help narrow it down.

Looking forward to your update! Are you able to check these things for me?

Already did All those on both samsung tablet and phone

Thanks for letting me know you've already tried all those steps on both devices. Since the standard notification settings and cache clearing didn’t resolve it, let's try a few additional, more detailed checks that often help with Rumble app issues on Samsung devices running Android 10:

1. Clear App Data (not just cache) for Rumble:
- Go to Settings > Apps > Rumble > Storage.
- Tap Clear Data. This resets the app to its initial state, so you'll need to log in again. Sometimes corrupted app data can block notifications.

2. Check Android System WebView Update:
- Since your device uses WebKit and Android 10, Rumble depends on Android System WebView for rendering and notification handling.
- Open Google Play Store, search for Android System WebView, and ensure it is updated to the latest version. If you see an "Update" button, update it.
- Restart your device after updating.

3. Restart Device After Clearing Data and Updates:
- Always do a full restart after these changes to ensure all background services reload properly.

4. Check for Any Device-Specific App Restrictions:
- On Samsung devices, there can be “Device care” or “Smart Manager” apps that automatically block background activity for battery saving.
- Open Device care > Battery > App power management, and make sure Rumble is NOT in the list of apps prevented from running in the background.

Doing the above often resolves persistent app behaviors where standard notification settings look correct but still do not work.

If it still doesn’t work after all these steps, it could be worth uninstalling and reinstalling the app completely to reset everything fresh.

Also, sometimes the issue may be on the Rumble server side or with the app update—so please keep the app updated regularly.
