Also should mention that I have not submitted the Tax Forms in App Store Connect. I believe that may be causing the issue.

The problem was solved when I filled out the bank and tax info.

Did you find any solution for this? I am getting the same error right now

Thank you so much!

I am trying to figure this out as well. My scenario is that I want to use the App Store Server Notifications as the definitive source for determining whether a user is subscribed to our service. Therefore, after they subscribe, it would be nice if the server notification happened in real time as stated, so that their status changes to subscribed on the server as soon as possible. Otherwise there will be a 30 second delay between the user subscribing, and the server knowing that the user has subscribed. But maybe this isn't how these server notifications are supposed to be used?

Just found this: https://developer.apple.com/documentation/appstoreconnectapi/app_store/auto-renewable_subscriptions/managing_auto-renewable_subscriptions To set a price point for another territory, use POST /v1/subscriptionPrices (Create a Subscription Price Change) again, replacing the subscriptionPricePoint ID with the other values you obtain from GET /v1/subscriptionPricePoints/{id}/equalizations (List All Subscription Price Point Equalizations). If the subscription is available in all territories, an individual POST /v1/subscriptionPrices call is necessary for each territory. You might consider automating this step.
