Unable to submit already approved subscription groups with error "New subscription groups must be submitted with an auto-renewable subscription from within that group.

Issue: Since Sept 10, 2026, my existing, already-approved auto-renewable subscription group cannot be submitted for review. This is not a new group: all 9 subscriptions in it show Approved, and my app has been live since July 2026.

How it started: I changed only the introductory offer (7-day to 14-day free trial) on the monthly products.

What App Store Connect shows now:

The group is marked “Prepare for Submission” with the banner “Your first subscription group must be submitted with a new app version.”
The Draft Submission contains only the group, and Submit for Review is disabled with: “New subscription groups must be submitted with an auto-renewable subscription from within that group.”
“Add for Review” is greyed out on every one of the 9 subscriptions, so there is nothing to add to the draft.

Impact: I can’t sell a subscription on any tier or billing period, and it has now been 6 weeks of lost revenue.

Not the app binary: Builds 497 and 501 were both approved within hours, with no effect on the group’s status.

What I’ve already tried, without success:

Attaching each subscription individually, with all metadata and review screenshots complete.
A forced re-save (editing a description, saving, reverting and saving again) to clear a stale validation state.
Removing and re-adding the draft submission.
Deleting and re-creating the introductory offer.
Resubmitting the app.
Accepting the latest agreements (all show Active).

Support status: Developer Support case 102961055291, opened Sept 12. I’ve provided screen recordings and screenshots. I was told the case would go to engineering, but in six weeks I haven’t had a reply from an engineer, a name or a timeline.

Two older threads describe the same stuck state and say it needed an Apple-side reset: 844425 and 818349.

Has anyone seen this resolved without Apple resetting it? And if an Apple engineer sees this, could the case be routed to the team that can reset the subscription group’s submission state?
