So as of right now is there a way to show the end to end app clip experience to folks using smart banner and iMessage? I have the QR code working but I can not get the other two to work. thanks.

liazkam, thank you much for quick response and info. I have been following your documentation/tutorials which have been a huge help. I didnt see your url with banner enabled html page so that also helps alot. I didnt publish my test app and just trying to test via testflight. my page with the banner meta tag is https:// op-ccmk.att.com/app-clip2.html and I (and other eyes I have asked) cant see anything wrong with it. since my app isnt published I used this url to find the app id https:// appstoreconnect.apple.com/apps/1528242909/testflight/ios/19d81f48-xxxxx but maybe that is why the app needs to be published? this is strictly a demo so I wasnt planning on publishing the app nor did I even think apple would approve it since there is no functionality really in the app. again thanks everyone - great information here
