IOS: Downgrade subscription

[Mihai-github]

Description

Trying to downgrade a subscription is not working, but upgrading works fine.

Expected Behavior

Be able to upgrade and downgrade subscriptions.

Screenshots

Environment:

• react-native-iap: 9.0.0
• react-native: 0.67.5
• Platforms (iOS, Android, emulator, simulator, device): iOS

To Reproduce
Steps to reproduce the behavior:

Both subscriptions are in the same group, and have the same subscription duration of 1 month but they have different prices

1. Initially buy a subscription with a higher price.
2. Downgrade to the lower price subscription

While downgrading and passing to the requestSubscription promise the SKU for the cheaper subscription an error occurred which also triggered the purchaseErrorListener.

This is the error from the purcahseErrorListener:

{
    "responseCode": "0",
    "code": "E_UNKNOWN",
    "debugMessage": "An unknown error occurred",
    "message": "An unknown error occurred",
    "productId": "_______"
}

[Optional] Additional Context

While debugging and inspecting my SANDBOX account, I noticed an interesting discrepancy: although the code caught an error during the subscription downgrade process, my account displays the subscription as active, despite the failure.

From my side. I can do the purchase.

Only error get the error "Error: An unknown error occurred" from requestSubscription when I try to downgrade

"react-native": "0.72.4", "react-native-iap": "^12.13.1",

React Native: 0.67.4
React-native-iap: 12.13.1 on StoreKit 2

Experiencing the same unknown error.
[Error: Purchased failed for sku:*Product ID Here*: Unable to Complete Request]

In my case, trying to downgrade from an Annual duration sub to a monthly duration - within the same subscription group.
Upgrading the same products works fine.

This was working on our previous setup using [email protected] on StoreKit 1

Do anyone think this is the issue from Apple's sandbox env :D

[ivannzme]

tried the below versions of the library:

• 12.13.2
• 12.13.1
• 12.13.0
• 12.12.2
• 12.12.1
• 12.12.0
• 12.11.0

React Native: 0.67.4

For the above, I am getting the same error message: [Error: Purchased failed for name_of_the_product: Unable to Complete Request]

Only getting this with iOS, android seems to be working as expected.
