App has been approved and in the app store.
However, my subscription localization status was rejected and my in app subscription does not work.
I have changed the localization description and re-submitted the subscription localization and group and they are now waiting for review.
Do I need to submit a new build on a new version? What am I to do if my app is in the store with not subscription access? How long doe subscriptions take for waiting for review?
From Submit an in-app purchase:
After you create an in-app purchase or subscription product in App Store Connect, you can submit it to Apple for review. If you’re submitting your first in-app purchase, you must submit it with a new version of your app. You can submit additional in-app purchases for your app on the App Store at any time. However, if you’re adding a new in-app purchase type to your app (for example, you usually offer consumables, but want to offer auto-renewable subscriptions), you must do so with an app version update. To submit an in-app purchase for review, it must have the Ready to Submit in-app purchase status. If it doesn't have this status, complete any missing information.
