Issue Description

There're some deprecated apple endpoints in fastlane: https://developer.apple.com/documentation/appstoreconnectapi/app_store_connect_api_release_notes/app_store_connect_api_2_3_release_notes#4165225

I was not able to check all of them but regarding https://developer.apple.com/documentation/appstoreconnectapi/list_all_available_territories_for_an_app
we should be using this endpoint:
GET https://api.appstoreconnect.apple.com/v2/appAvailabilities/{id}/territoryAvailabilities
and NOT this:
GET https://api.appstoreconnect.apple.com/v1/apps/{id}/availableTerritories

Do we have a plan to start using new endpoints?

Thanks a lot

Hi, there is a PR #21901 with an implementation for request to get app availabilities, please take a look at the description there. For now it's left as a draft as there is one PR (#21900) that should be finished in the first place.

Thanks,

This is fantastic, shall fix all the price_tier and App has no prices yet... Enabling all countries in App Store Connect errors we are seeing with Deliver.

I hope this can be added soon. We work with a white label app, and im creating 5-10 new apps on new accounts every week, and its very annoying that this cannot be done. I had it scripted that fastlane would do it all, but now it crashes everytime it has to submit a new created app for review. So i have to go in manually and set the territory and pricing and then run fastlane to submit again. It has been like this for a very long time now.
