There are no additional steps required from you. Once your app and app clip are live, the registered URLs for the advanced experience will automatically start working. Can anyone tell me: What is "live" mean?
Will it work on testflight env, I need to test it before -publish to production?
Is status Received live?
The second question:
I scan a QR code, it tell me that:
"The app clip is not currently in your country"
Selecting any option will automatically load the page
