Hi there! I understand that you're having trouble scanning QR codes with the Alinea app on your iPhone running iOS 18.7. To help you better, could you please tell me a bit more about the issue? For example, does the camera open but not recognize the QR code, or does it fail to open the scanner at all? Also, are you able to scan QR codes using other apps or the iPhone’s built-in Camera app?

Meanwhile, here are some initial steps that often help resolve QR code scanning issues in apps:

1. Check Camera Permissions: Go to Settings > Privacy & Security > Camera, and make sure Alinea has permission to access your camera.

2. Lighting and Distance: Ensure you're in a well-lit area and hold your phone steady about 6-12 inches from the QR code. Sometimes being too close or too far can affect scanning.

3. App Update: Verify that the Alinea app is updated to the latest version via the App Store.

4. Restart the App/Phone: Close the app completely and reopen it, or try restarting your iPhone.

5. Try the iPhone Camera: Open your regular Camera app and point it at the QR code to see if it recognizes it. This can help isolate if the issue is within the app or the device itself.

If you’ve already tried these or if the issue persists, let me know what you have attempted, and we can look deeper into settings or possible app-related issues.

Are you able to try these steps and share what you observe?
