If your TMZ app is presenting a black screen upon opening, you can follow these steps to try and resolve the issue:

1. Restart Your Device: A simple restart can often fix many app-related issues. Turn off your device completely and then turn it back on.

2. Update the TMZ App: Ensure that you have the latest version of the TMZ app installed. Go to the App Store, search for TMZ, and check if there is an update available. If so, install it.

3. Reinstall the App: Uninstall the TMZ app and then reinstall it. This can often clear up issues related to corrupted app data. To uninstall, press and hold the app icon until it jiggles, then tap the 'X' to delete it. After that, go to the App Store to download it again.

4. Check Permissions: Make sure the app has the necessary permissions to function properly. You can check this in your device's settings under Privacy.

5. Clear Cache (if applicable): If you are using an Android device, clearing the cache of the app might help. Go to Settings > Apps > TMZ > Storage, then tap on 'Clear Cache'.

6. Check for System Updates: Sometimes, an outdated operating system can cause compatibility issues with apps. Go to Settings > Software Update and make sure your device is up to date.

7. Look for Known Issues: Occasionally, the problem may be on TMZ's end due to server issues. You might want to check forums for others experiencing the same issue or any announcement from TMZ about known problems - learn more - learn more - learn more.
