Over the last 48 hours (Since Dec 4th) for me, the List All In-App Purchases route is timing out for several different apps. Either the initial request times-out or the paging next token request times out.
https://api.appstoreconnect.apple.com/v1/apps/{id}/inAppPurchasesV2
https://developer.apple.com/documentation/appstoreconnectapi/list_all_in-app_purchases_for_an_app
Other routes like listing apps seem to work. https://api.appstoreconnect.apple.com/v1/apps
The developer status page does not list any outages.

Where is the correct place to report issues with AppStore Connect API services?
