I added auto renewable subscriptions to my app. First submission of IAPs require a new build along with it. I tested everything locally through the .storekit file. Everything worked perfectly so I submitted it for review.
The moment I did so, StoreKit.Product.products(for:) stops returning the products. If I click on the "Sync" button on .storekit now the pre-existing subscriptions disappear. Apple reviews the build and states that there are no subscription options visible.
Also in "Prepare for submission" phase, IAP & Subscriptions section disappears so one can no longer add them to the next builds.
I have tried to explain this 7 times (with new version submissions) through App Review Comments. It looks like nobody reads the responses. I tried adding the issue as a note, screenshot, video in different parts of the submission. They are entirely ignored. I sent 3 support request none of which have resulted in a response. I tried setting up a 1 on 1 call with Apple and it got rejected.
This issue has been reported by other people in this forum and others with no solutions provided.
I am completely out of options at this point. If I and others are indeed right to think that there is a bug in App Store Connect on the specific scenario with first time IAP review submissions where the first build is rejected by developer's fault, it bugs out with subscriptions.
My app's success entirely depends on this as I can't monetise it and I am in Apple Developer Program which means I am subscribing to this service. Can someone from Apple Team, please respond to this specific issue on whichever medium chosen. I am completely blocked and in dire need of help.
Thanks for your understanding.
