@Verara20 And it was public unlisted app from the beginning. What do you mean exactly? Was it a public app or an unlisted app? 🙂 This AASA file works for us: { "applinks":{ "apps":[ ], "details":[ { "appID":"MYTEAM.com.example.myApp", "paths":[ "/native_app/*" ] } ] }, "appclips":{ "apps":[ "MYTEAM.com.example.myApp.appclip" ] } } As mentioned, we haven't changed anything except re-publish the app as a public app again. We left the old unlisted app active for the moment so that the problem can be reproduced more easily. Unfortunately, the error is still present, also in 26.1 beta3.

@Verara20 Interesting discoveries, thank you for sharing. 🙏🏻 In the meantime, since we didn't see any other option and we didn't get a response in the feedback either, we published the same app again as a public app... and lo and behold, it works with iOS26 without any problems, even though we didn't change anything in the structure of the entitlements or the aasa file. So it seems that the problem was indeed that it was an unlisted app with appclip.

@pumpkinpaul You can access the console of a connected device this way in Xcode:

@Verara20 May we ask which app/AppClip is affected in your case? We are currently only experiencing this error with one AppClip, but another one (for a completely different app/development team) is working fine. So we are still trying to figure out why one works and the other doesn't. The app that isn't working for us is an unlisted app. At first, we thought that might be the reason, but we simply don't know. It's depressing that we can't do anything at the moment to get the solution working again with iOS26. The console log shows that there are some requests that are going wrong and that didn't happen with iOS18. error 15:05:16.940931+0200 appstored AMSURLSession: [F50720EC] Session decoder failed.

Is there anything we can do to get it working again? Could it be because it's an unlisted app? Unfortunately, it's very critical for us that this solution no longer works with iOS26.

I opened a feedback and the number is FB20169481
