A. 1. Check your internet connection: Ensure that you have a stable and fast internet connection. You can do this by running a speed test on your device. If your connection is slow, try resetting your router or connecting via an Ethernet cable instead of Wi-Fi. 2. Clear the app cache: Go to your device settings, find the Zattoo app, and clear the cache. This can help resolve any temporary data issues that may be causing the app to freeze. 3. Update the app: Make sure you are using the latest version of the Zattoo app. Go to your device's app store, search for Zattoo, and check for updates. If an update is available, install it and restart the app.

B. 4. Restart your device: Sometimes, simply restarting your device can resolve performance issues. Turn off your device completely, wait a few seconds, and then turn it back on. 5. Reinstall the app: If the problem persists, uninstall the Zattoo app and then reinstall it from your app store. This can help fix any corrupted files that may be causing the freezing.
