Hi there! I see you're having connection issues with your FreeStyle Libre 3 app on your iPhone. Let's get this sorted out together.

To start, could you tell me a bit more about what exactly is happening? For instance:
- Is the app not detecting the sensor at all, or is it losing connection intermittently?
- Do you see any error messages or alarms like a "signal loss" notification?
- Have you tried scanning the sensor with your iPhone and does it respond?
- Is Bluetooth enabled and allowed for the LibreLink app in your iPhone's settings?

While waiting for your feedback, here's a straightforward step-by-step to try:
1. Make sure your iPhone is within about 33 feet (~10 meters) of the sensor, as being too far can cause disconnection.
2. Check that Bluetooth is turned on (Settings > Bluetooth).
3. In your iPhone settings, go to Settings > LibreLink app and confirm Bluetooth permissions are enabled.
4. Restart your iPhone: press and hold the side button and either volume button, then slide to power off. Turn it back on after a minute.
5. Try scanning the sensor again with the LibreLink app.
6. If connection issues persist, toggle Airplane Mode on for 10 seconds and then off to reset wireless connections.
7. Ensure your LibreLink app is updated to the latest version via the App Store.

If these don't help, we can look into resetting network settings or reinstalling the app—but I’ll guide you carefully on those to avoid losing your data.

Does any of that align with what you’ve already tried or observed? Let me know so I can tailor the next steps!

Looking forward to your reply!
