Hi! I see you're having trouble with the Australian ETA app's Live Photo feature on your iPhone, and it's giving a "service not available" message. Let's see if we can get that sorted out for you.

To start, could you tell me if you've tried any steps so far? For example, have you closed and reopened the app, or tried restarting your phone? Also, is your internet connection stable and strong when you attempt to use the Live Photo feature?

In the meantime, here are some common steps that often help fix this kind of issue:

1. Check your Internet Connection: Make sure you're on a stable Wi-Fi or cellular network. A weak or intermittent connection might cause service availability problems.

2. Restart the App: Swipe up from the bottom of your iPhone screen to open the app switcher, then swipe the Australian ETA app off the screen to close it. Reopen it afterward.

3. Restart Your iPhone: Simply turn your device off and back on. This can clear temporary glitches.

4. Update the App: Make sure the Australian ETA app is updated to the latest version available in the App Store.

5. Reinstall the App: Delete the app, then download and install it again. This can help clear any cached data that might cause problems.

6. Check Photo Settings: Sometimes, the app requires camera permissions. Go to Settings > Privacy > Camera and ensure the Australian ETA app has permission to use your camera.

7. Reduce Photo Size: Some users report that very high-resolution photos cause problems. Try taking a simpler Live Photo or use a different lighting environment for better recognition.

If after trying these the problem persists, it might be a temporary service issue on their side, which does happen occasionally. If that's the case, trying again a bit later often resolves it.

Let me know how you go with these steps or if you've already tried some of them! I’m here to help further.

Are you satisfied with this approach so far?
