App Clip not showing in TestFlight

My app / App Clip was successfully uploaded & processed by appstoreconnect, and 2 invocation urls are configured in TestFlight.

I checked that the invocation urls in configured in TestFlight match the "appclips:" associated domains configured in the App Clip target (XCode).

Yet the option to test the App Clip are not shown when accessing the uploaded build as an internal tester in there TestFlight (on an iPad running iOS14.01).

What could I possibly be missing?


I forgot to mention I also checked that my apple-app-site-association can be GET'd from https://[my-associated-domain]/.well-known/apple-app-site-association, and that the json array returned does contains the app clip info like so

Code Block
{
"appclips": {
"apps": ["ABCED12345.com.example.MyApp.Clip"]
}
}

Addendum, the WWDC video Whats new in App Store Connect, says from 14:24


If you want to check the validation status of your App Clip, go to the build details page in App Store Connect.
From here, click the View Status link in the App Clip section, and this will bring up a modal showing domain validation status.



Well ....no App Clip section for me on the build details page, though the Store Information section does show the App Clip's application identifier (and other info related to the App Clip embedded with the App)
Please file a bug report including the following details about your app and app clip:
  • Team ID

  • App clip bundle identifier

  • Associated Domain path to Apple App Site Association file

  • Associated Domains in app clip target

  • Screenshot of current app status in App Store Connect

  • Any additional details that you feel may be pertinent
