This is the documentation that I'm trying to follow: https://developer.apple.com/documentation/storekit/in-app_purchase/testing_in-app_purchases_with_sandbox/testing_disabling_auto-renew The issue happens during step 3

I'm facing a similar issue, except for me I'm directly going into settings > apple id > subscriptions > click on the subscription item > Cannot Connect. Testing on a physical iphone device with my sandbox account logged into the app store.
