Hey @liazkam,
Edit: An Apple Engineer replied to another thread here stating that the Smart Banner won't be live until iOS 14 is released:
https://developer.apple.com/forums/thread/657921I got my App Clip submission working I think the day after beta 6 dropped (compiled/uploaded via Xcode 12 beta 6). So far, I managed to get the Advanced App Clip submitted with one of my domains for demo purposes after much trial and error with the associated domains. From what I can tell, everything is setup on my end property to get the banner / app clip card to show when visiting my domain but I don't see either showing up. Additionally, when I do an iMessage with my domain url to an iOS 14 devices, the experience isn't showing up there either. It is hard to tell what is live and what is still pending developer release on Apple's side.
My "Experience URL Status" under the Advanced App Clip Experiences is set to "Received". I couldn't find documentation on the different status values. What does yours show? I'm wondering if there is a status that represents something to the effect of 'live in production'.
With that having been said, I can invoke the App Clip itself via test flight, and then it shows up in Settings > App Clips and can be removed from there.
NOTE: If anyone has issues submitting their binary and having it show up with the correct associated domain capability--your associated domain app clip listing should NOT include https://, but when you setup your advanced app clip, you do need to specify the https protocol.
I created a suggestion feedback FB8581967 requesting more documentation details around the associated domain app clip tag requirements.
