Thank you for your response. I followed your steps until step 7. After the first command (I think it shows the entitlements file?) I can't see any multicast entitlement... only some identifier and other stuff. The second command unfortunately doesn't work, it says directory not found. In Payload I only see my apps name.

Can you post the actual results? I’m flying blind here! Sure. It looks like this: dict keyapplication-identifier/key stringMyTeamIdentifier.de.cartesy.CartesyLivestream/string keybeta-reports-active/key true/ keycom.apple.developer.team-identifier/key stringMyTeamIdentifier/string keyget-task-allow/key false/ /dict Oh, and my previous post failed to do that properly, where the second command uses Test747881523.app rather than YourApp.app. Sorry about the confusion. I tried the command again and now it worked. Also I can see the multicast entitlement in there. .... keyEntitlements/key dict keybeta-reports-active/key true/ keycom.apple.developer.networking.multicast/key true/ ..... others ..... /dict keyExpirationDate/key

I already added com.apple.developer.networking.multicast in my .entitlements file. It works when I start the app from Xcode. That's why I'm confused that it's not working from App Store but from debugging.

I think I found out the issue, but I'm not sure yet. I just realized there is another .entitlements file for Release (shows up in Finder). I didn't know that because it doesn't show up in my Xcode project navigator. So there are 2 .entitlements file. And in the Release.entitlements file there is no "com.apple.developer.networking.multicast" inside it. I'm uploading my app to TestFlight at the moment and I will give feedback when I tested the new version. UPDATE The app finally works. So at the end I just had to add "com.apple.developer.networking.multicast" to the Release.entitlements file and set Value true.

Yes, I did. When I refresh the page, all screenshots are gone. Then I try to add some new but they are only blurred and "loading". It feels like it's a bug and I can't do anything myself.

Now it finally works. I didn't do anything. Seems like you have to wait until uploading works again.
