Hi! I understand your BlockDAG X1 app mining has stopped and the "Active" button is inactive, and you also can't restart the app. Let’s work through this so you can get mining again.

First, could you let me know if you’ve tried closing and reopening the app or restarting your device since the issue started? Also, have you checked if there are any updates available for the BlockDAG X1 app on your Android 10 device?

Meanwhile, here’s a step-by-step approach that usually resolves this:

1. Clear Cache:
- Go to Settings on your Android phone.
- Tap Apps or App Manager.
- Find and select BlockDAG X1.
- Tap Storage and then Clear Cache only (don’t clear data yet).
- After clearing cache, reopen the app and see if the Active button works.

2. Force Stop and Relaunch:
- Still in the BlockDAG X1 app info screen, tap Force Stop.
- Close the app entirely and reopen it to see if that reactivates mining.

3. Check for App Update:
- Open the Google Play Store, search for BlockDAG X1, and confirm it is updated to the latest version. Updates often fix bugs with activation and buttons.

If those don’t work, you might need to uninstall and reinstall the app, but let’s try the above first since that tends to fix the inactive button and restart issues for most users1 4.

Could you try these and tell me how it goes? If it’s still inactive, we can dig a little deeper into your device’s settings or check for any account-related issues.
