Help in Android subscription downgrade with DEFERRED mode

[JameDodgers]

Hello there,

Could you guys help me to understand what exactly should I do when trying to perform a subscription downgrade on Android? Currently when I call requestSubscription() with ProrationModesAndroid.DEFERRED my listener gives me the same purchase object that I'm downgrading from. If I try to call finishTransaction() upon that purchase it gives me the error "purchase is not suitable to be purchased".

Expected Behavior

Based on the discussions in #888, I believe that the value returned in currentPurchase would be null and I wouldn't need to handle it because the subscription change will be notified to my backend serve by the real-time developer notifications.

Thanks in advance.

Environment:

• react-native-iap: 9.0.4
• react-native: 0.66.4

Correct, you can't finish that transaction on the client. Your backend will get the update and you have to acknowledge it there

@andresesfm But what should I do with the currentPurchase? Keep spamming my backend server with it? As my backend will receive the notification when the billing period ends, is there a way to know if a purchase is in this state to prevent sending it to my backend? Sorry if I was not clear
