App Store Connect cannot delete the app, as it shows that in-app purchases are under review, but no IAP or subscription items can be seen on the front page.

I want to delete an app from App Store Connect, but I've been unable to do so. App Information:

• App Name: Need to be removed-MI
• Apple ID: 6742525904
• Current Status: Prepare for Submission

I have already followed Apple's official guidelines for removing the app: https://developer.apple.com/help/app-store-connect/create-an-app-record/remove-an-app/

The following operations have been completed:

1. App information has been reset;
2. All in-app purchases have been deleted/cleared;
3. All subscriptions and subscription groups have been deleted/cleared;
4. The app has been removed from all sales regions;
5. App Review Submission has been removed;
6. The submission record in the App Review page now shows as Removed;
7. Logged out and re-logged into App Store Connect;
8. Browser cache and history have been cleared;
9. Attempted to repeat the process using Safari for Mac and different network environments.

Currently, when deleting the app, a prompt still appears: “This app is unable to be removed right now.

This app cannot be removed. Learn more about removing apps.

This app has in-app purchases that are in review. Please try again once these in-app purchases are no longer being reviewed.”

The previous error message also included: “Some items related to this app are currently in review. To remove this app, you must first cancel the submission.”

However, after removing the App Review Submission, this section has disappeared, and only the prompt related to "in-app purchases that are in review" remains. Currently on the App Store Connect front-end page:

• The In-App Purchases page is empty;
• The Subscriptions page contains no subscription items or subscription groups;
• App Review submission history has been removed;
• The app is currently in the Prepare for Submission state;
• No IAPs, subscriptions, or submissions currently under review can be found.

Previously, the Subscriptions page displayed a notice: “One or more of the subscriptions listed below requires your attention.”

However, the page does not display any subscription items or subscription groups.

I'd like to ask if anyone has encountered a similar situation: the front-end page no longer shows any IAP or subscription items, yet when deleting the app, it still prompts that in-app purchases are under review?

Is this situation due to residual IAP/Subscription review statuses left behind by Apple's backend, requiring contact with Apple Developer Support for cleanup? Or is there another hidden entry in App Store Connect that can be used to remove these lingering items?
