More or less the same issue. App stuck in Waiting for Review. Also: since about a week my sales have dropped by 80%. Could be coincidence but I feel something is up with the App Store....

After some research, it looks like Xcode 16.4 does not support Challenges yet. It should become part of the next major version of Xcode (version Xcode 2026) as it is mentioned in the release notes: https://developer.apple.com/documentation/xcode-release-notes/xcode-26-release-notes Still very weird that Apple is demoing this at WWDC and not mentioning that you need to work on the beta of Xcode to get it to even work..... I have not yet tried Xcode 26 to see if it is working....

Thank you but I did/do not attend WWDC25. Is there any other way you can help? How can I see challenges in App Store Connect?
