@lyonlui we have the same issue with one of our app clips. I have the same error in the Diagnostics under Settings > Developer, which goes away if we force-reset the app clip cache ("Clear Experience Cache"). That is however not a solution, just a hack to refresh some local cache on the iPhones. How did you solve your problem? Did you submit a new build and asked reviewers to double-check they successfully deploy app clip experiences?

Is there no feedback on this issue? I can't believe that nobody is using prefix matching for their app clips, given that it's a largely advertised feature. According to the docs you can specify an advanced experience with URL https://appclip.example.com that would then be triggered by all URLs that match the prefix https://appclip.example.com/shop https://appclip.example.com/bike?q=123 Did anyone get this to work? I setup my advanced experience exactly like that (https://mydomain) and still all QR codes and app-clip codes pointing to https://mydomain/whatever do not open the app clip. The only thing I am getting so far is a message "No usable data found" (see imgur.com/ckQIDAm). Looking forward to some feedback on this -- I have been struggling for more than one week on enabling this feature in the App Store. Thanks Alessandro
