Hi there! I'm sorry to hear you're encountering a "source error" with CUE Live. Let's work together to resolve this.

First, could you share any specific details about when this error occurs? For example, does it happen when you're trying to stream a specific video, or is it a general issue across all content? Knowing this can help me guide you more effectively.

In the meantime, here are a few troubleshooting steps that might help:

1. Restart the App: Sometimes simply closing the CUE Live app completely and reopening it can resolve temporary issues.

2. Power Cycle Your Device: Unplug your device (if applicable), wait for about 10 to 15 minutes, then plug it back in. This can refresh the connection.

3. Check Your Network Connection: Make sure your iPhone is connected to a stable Wi-Fi network. You can try toggling Airplane Mode on and off to refresh your connection.

4. Logout and Re-login: If you're still getting the error, try logging out of your CUE Live account and then logging back in.

If you've already tried some of these steps or if the issue persists, please let me know, and we can look into more advanced solutions!
