I contacted Apple regarding this issue, but I haven't received any response. My app is currently live, along with subscriptions and the services associated with them. From a user experience perspective, the situation is extremely poor. Moreover, if such an issue exists, why wasn’t my app thoroughly tested before going live? I urgently request Apple to resolve this problem as soon as possible.

Hello, I am experiencing the exact same issues. My app was published on the App Store today, but the subscription features are not working within the app. On the subscription page, it says “Waiting for Review” under my subscription products. Were you able to solve this problem? Please let me know.
