Since last week while testing our in-app purchases with a sandbox account, I often wait for a minute or longer to receive any feedback from the app store. This is the case within the app but also in the developer settings -> sandbox account -> subscriptions.
My task is to implement subscription management with a third party server. This sadly prevents me from using StoreKit2 and the transaction manager within XCode, which I've enjoyed in the past. Testing with sandbox accounts is extremely frustrating due to these problems.
Other posts on this forum have highlighted similar issues so I want to ask: what is the cause and when can we expect a stable version again?
