To resolve the issue of the SuperLive Plus app not working on your iPhone after the last update, follow these steps:

1. Check Internet Connection: Ensure that your iPhone is connected to the internet, either through Wi-Fi or mobile data. A weak or unstable connection can cause the app to show a "no data" message.

2. Restart the App: Close the SuperLive Plus app completely and then reopen it. This can refresh the app and resolve temporary glitches.

3. Update the App: Go to the App Store and check if there is an available update for SuperLive Plus. If there is, download and install it. Developers often release updates to fix bugs and improve performance.

4. Reinstall the App: If updating does not fix the issue, try uninstalling the SuperLive Plus app and then reinstalling it. To uninstall, tap and hold the app icon until it shakes, then tap the "X" or "Remove" option. After that, go to the App Store to download it again.

5. Check Permissions: Ensure that all necessary permissions for the app are enabled. Go to Settings > Privacy > Camera and ensure SuperLive Plus has access to your camera and any other required features.

6. Contact Support: If the problem persists, consider contacting the app's support team for further assistance. You can usually find support contact information within the app or on the App Store page.
