Hi there! I understand that when you try to update the DraftKings Sportsbook & Casino app on your Android device, you get a screen prompting you to update, but tapping it does nothing. Let's work through this together.

First, could you tell me if you tried updating the app through the Google Play Store directly or only through the in-app prompt? Sometimes the automatic update prompt can be stuck, and manually updating the app works better.

Assuming you haven’t tried the Play Store yet, here’s a step-by-step approach:

1. Manually Update via Google Play Store
- Open the Google Play Store app on your Android device.
- Tap the menu icon (three horizontal lines) or your profile icon, then choose "My apps & games."
- Look for DraftKings Sportsbook & Casino under the "Updates" tab.
- If it appears, tap "Update" to install the latest version.

2. Clear the Google Play Store Cache
If the update option is not showing or doesn’t work, clearing the Play Store’s cache can help:
- Go to your device’s Settings > Apps > Google Play Store.
- Tap on "Storage & cache."
- Select "Clear cache" and then "Clear storage" or "Clear data."
- After this, reopen the Play Store and try updating DraftKings again.

3. Restart Your Device
After clearing cache, restart your phone. This refreshes system processes.

4. Check Network Connection
Make sure you have a stable internet connection. Try switching between Wi-Fi and mobile data.

5. Uninstall and Reinstall the App
If updating still doesn’t work:
- Uninstall the DraftKings app from your device.
- Then go to Google Play Store, search for DraftKings Sportsbook & Casino, and reinstall it.

6. Check Device Compatibility and OS Version
Your Android 10 OS should be compatible, but the latest app version might require a minimum OS version. Confirm you have enough free storage space as well.

Please try these and let me know where you get stuck or if anything changes. I’m here to help! Are you able to access the Google Play Store to try the manual update?
