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?
I'm not sure about whether you'd need to resubmit a build or not. But it should only take a couple days at most. Apple review teams seem to be reasonably quick at the moment, even though it's the festive season.
did you get your localization approved?
Stuck in the same boat and now my app is live but broken since you can't get past without purchasing at least free trial. Were you able to resolve this?
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.
