Hi there! I understand that you're experiencing a black screen when trying to select a book in the hoopla Digital app on your Kindle. Let’s work together to resolve this.

First, could you let me know if you've tried any troubleshooting steps already? For example, have you attempted to restart the app or your device? Any specific actions you've taken can help narrow down the issue.

While I wait for your response, here are some common solutions that might help resolve the black screen issue:

1. Restart the App: Close the hoopla app completely and then reopen it to see if the issue persists.

2. Check for App Updates: Open the Google Play Store on your device, search for the hoopla app, and see if there are any updates available. If there are, please update the app.

3. Clear Cache: Go to your device's Settings > Apps > hoopla. Tap on Storage, then select "Clear Cache." This may help improve app performance.

4. Uninstall and Reinstall: If the steps above don't work, try uninstalling the hoopla app and then reinstalling it from the Google Play Store. This can fix bugs and refresh the app.

Please give these steps a try and let me know how it goes or if you've already attempted any of these solutions!
