Same problem here, when i received email about app approval in that same mail was even confirmed that subscriptions was approved too. But in the app downloaded from store there is no any subscriptions and on the appstoreconnect page about subscriptions still a message that "Subscription returned. The information is given in the table below." but all the information there is only that subscriptions and localization are "Waiting for review" what really looks like a contradiction to the email that confirms that all (an app and the subscriptions) was approved. Contacted support about that problem via email, still waiting for some help 🤷‍♂️
