Tested environment (Emulator? Real Device?)

Android device

Steps to reproduce the behavior

1. Set up a subscription in App Store Connect
2. Purchase the subscription from app using RNIap.buySubscription()
3. Run RNIap.getPurchaseHistory() and look at the transactionId property of the result

getPurchaseHistory is used only in non-consumable product. You should use getAvailablePurchases instead and that's written in the readme.

[gerbus]

Thanks @hyochan. I was confused when initially reading the README about those.

[gerbus]

@hyochan actually the result of getAvailablePurchases() is an empty array. As stated in the readme:

Once an item is consumed, it will no longer be available in getAvailablePurchases() and will only be available via getPurchaseHistory().

What I am trying to do is get the transactionId of the most recent purchase.

[gerbus]

I've updated Actual Behavior in case it's not clear what I'm seeing.

[hyochan]

@gerbus Sorry friend. I was confused. You are right. However, this is duplicate in #385.

[gerbus]

Hmm. Looks like the issue in #385 is a fully empty array, no? Just wanting to make sure this is in fact a duplicate of that, because for me the array is full except for the transactionId property.

Appreciate the prompt responses @hyochan!

[hyochan]

@gerbus Then this might not be an issue and I think this is expected since transactionId only appears when there is no finished transaction (which means the transaction is not done yet). Helpful Read.
