Hi! I see you're having trouble with task notifications not working consistently on your Focus To-Do app, even though you've already given all necessary permissions. Let's get to the bottom of this together.

First, can you tell me if you've noticed whether the notifications fail at specific times or conditions? For example, does it happen when your phone is locked, or during certain hours? Also, have you checked if any "Do Not Disturb" or Focus modes might be enabled on your Android device that could be silencing notifications?

While you check on that, here are some steps to try that often resolve such issues on Android 10 devices:

1. Confirm Notification Permissions Again
Even if permissions are granted, it's good to double-check:
- Go to your phone Settings > Apps > Focus To-Do > Notifications and ensure notifications are fully enabled.

2. Disable Battery Optimization for Focus To-Do
Android sometimes restricts background activity to save battery, which can delay or block notifications. To prevent this:
- Settings > Battery > Battery Optimization
- Find Focus To-Do and set it to Don't optimize.

3. Check Do Not Disturb or Focus Modes
- Make sure Do Not Disturb is off, or if on, that it allows exceptions for Focus To-Do notifications.

4. Verify App Notification Sound and Volume
- Open Focus To-Do, check reminder and notification sound settings, and ensure your phone’s media and notification volumes are up.

5. Clear Cache and Data (only if you don’t mind re-logging in)
- Settings > Apps > Focus To-Do > Storage > Clear Cache.
- If issues continue, try "Clear Data," but be aware it resets app settings.

6. Update or Reinstall the App
- Ensure you have the latest version from Google Play Store. If you already do, you might want to uninstall and reinstall to clear any corrupted files.

Please try these steps and let me know how it goes. If notifications are still inconsistent after that, I can guide you through some more advanced checks like reviewing network restrictions or account sync settings.

Are you able to perform these steps now?
