Cannot modify user's subscription in iOS

basakserit commented 6 years ago

I am trying to modify subscription of the user from app inside within the same subscription group. During PurchaseAsync first pop-up is for confirming the purchase which is "Do you want to upgrade to 1 Month auto-renewable subscription? Your upgrade will start now. You'll receive a refund for the remaining time of your 1-year subscription to yearly auto-renewable." After clicking "Continue", I got a General Error as below. Is the issue related to refunding and sandbox?

Exception: Plugin.InAppBilling.Abstractions.InAppBillingPurchaseException: Cannot connect to iTunes Store

Bug Information

Version Number of Plugin: 2.0.0 Device Tested On: iPhone 6p Version of VS: 7.5 Version of Xamarin: Xamarin.iOS Version: 11.6.1.4

Steps to reproduce the Behavior

User A buys a subscription with his Apple ID.
User A updates his subscription with the same Apple ID.
The system displays a pop-up for confirmation
The system throws an error which is "General Error, Cannot connect to iTunes Store"

Expected Behavior

Users should update their subscription with the other ones which are in the same subscription group.

I could look into this one too as soon as my colleague will enable subscriptions on apple store (should be in the next weeks). @jamesmontemagno : from a plugin point of view this functionality can be paired with the one I'm fixing in #26 on the android side, do you agree? Can you approve (or reject) my pull request for the Android part and I will extend it if it is needed to fix this bug?
