In app purchase “Cannot connect to iTunes Store” error for Sandbox user

Have also error witch sandbox
ios 12, xcode 11

As a sandbox user, entered password twice. Then the transaction fails.

I can confirm. 
The same thing is working in iOS 14

Apple, please help !!!

I got rejected on an update submission because on iPad with iOS 14.0.1 sandbox won't work and will ask for login twice. On iPhone everything is fine. Any ideas ?

The issue has still existed for 2 days in my case.

The error says Error Domain=SKErrorDomain Code=0 "Cannot connect to iTunes Store"

I am testing on iOS12 device with a new sandbox account.

Anyone gets it solved?

Same problem.

In-App dialog is showing twice, after that it fails with error "Cannot connect to iTunes Store" (iOS 13.2)

Same here.
In-App dialog is showing twice, after that it fails with error "Cannot connect to iTunes Store".
Multiple users and devices.
iPad mini iOS 12.4.8
iPhone X 13.x? tester
Xcode 11.3.1
OSX 10.14.8
Waiting for a iOS 14.x tester

I can retrieve the description and price. I present the user with a dialog before I start the purchase process. So I can communicate to the iTunes store but can't complete a purchase in the sandbox.

I have the distribution version waiting to be released but I'm afraid that all the users will start calling.
How can this not be addressed ASAP? I'm dying here...

I am also experiencing this issue.

Using Xcode 12.0, I am seeing the same "double prompt" for password, which is then followed by this error:

Error Domain=SKErrorDomain Code=0 "Cannot connect to iTunes Store" UserInfo={NSLocalizedDescription=Cannot connect to iTunes Store}

This is happening on devices running iOS 11.x < iOS 13.x.

As others have stated, this does not occur on iOS 14 devices. I tried purchasing both consumable IAPs, and Renewable Subscriptions. Both have the same result. Test Flight builds that perform purchases using non-sandbox Apple IDs seem to work without any issue on any OS.

Same issue. Using Xcode 12.0.1 - And getting double prompt for login credentials. I am able to use Sandbox test account with iOS 14.0.1. However, iOS 13 and below are returning error - "Cannot connect to iTunes Store".

Noticed that if you get IAP prompt with title "Subscription terms" - It will eventually land into "Cannot connect to iTunes Store" error.

My code uses SwiftyStoreKit wrapper around StoreKit API. I was debugging more into, but it seems to be error within Apple ecosystem.

Update the OS version to 14, and it turns out that the sandbox purchase succeed.Thank god.

I am facing the same issue in iOS 13.6

An in-App dialog is showing twice also entered the password twice, after that it fails with Transaction Error: "Cannot connect to iTunes Store". I even tried creating a new sandbox test user and still run into this same error.

same here.
does anybody else think it is sdk 14 issue?

I don't think so. The linked issue is talking about Xcode 12 with iOS 14 SDK, while here we have exactly the opposite - at least in my case - Xcode 11.7 with iOS 13 SDK. Also other people explicitly mentioned being on Xcode 11 still.

Updated device OS version 13.6 to 14.1 and it is working.

I think there is a fix on server side from Apple, everything should work now :) I guess with all SDKs.

I started working for my iOS 12 and 13 testers this morning EDT.
Whew...

Thanks Apple for getting to the bottom of this!
