We have subscriptions for our app that are in the "waiting for review" state. The subscriptions page has the message "Your first subscription must be submitted with a new app version. Create your subscription, then select it from the app’s In-App Purchases and Subscriptions section on the version page before submitting the version to App Review."
However I don't see any section in the app to enter this. It seems to be a similar issue to what is being described at https://stackoverflow.com/questions/73098652/app-store-connect-in-app-purchase-and-subscriptions-section-missing?rq=2, but I have all requirements fulfilled; all compliance and tax forms have been completed, and I have made changes to my subscriptions in response to app review.
I did add these subscriptions to my app in a previous round in the approval process, and I thought that was why it wasn't appearing now. However, my app is now live and users are not seeing the subscriptions options when they try to enter the app (which had previously worked in sandbox mode)
