@JJMoon Can you read this? I don't quite get how this process resolve #279.

@lwansbrough Hi. I need your help on this PR. Do you think we need to call another async and await to ensure the finishes of the function? I feel like it is quite redundant. #279 was resolved with doing this fixes but I am still not sure why we need this. Or could be a better way.

[LinusU]

This removes the return value from these functions, there was nothing wrong with them before.

Could this please be reverted?

[hyochan]

@LinusU I felt this is quite weird too. However, @JJMoon swear to god that this should be done to fix #279. I've just looked into this one and feels like this wasn't the solution and it was just fragile linking problem which we should just unlink and link again. What do you think @LinusU @JJMoon ?

[LinusU]

It's possible that Babel is rewriting the async function in some way that makes the Promise resolve later in the microtask scheduling queue than before, but I don't see how that could possibly affect anything 🤔

[hyochan]

@LinusU Ok. I'll try to revert this tomorrow if I don't receive any other feedback on this. Especially from @JJMoon.

[hyochan]

@LinusU Wouldn't this be fine tough?

async () => RNIapIos.buyProduct(sku),

I've just looked in the code and saw that I've already gave some updates.

[LinusU]

The async there won't do anything, I would recommend keeping it as () => RNIapIos.buyProduct(sku)

[hyochan]

@LinusU Yes. This is just another Promise resolver. Ok I'll change this now then.

[hyochan]

@LinusU Done it!. @JJMoon Please check if you have any opinion on this release because you've told me to make changes to include async earlier. Thanks.

[JJMoon]

@hyochan It looks my PR is merged. It's OK. Thanks

[hyochan]

@JJMoon That wasn't what I was saying. The changes you've made which you swear to god to make all the functions to async, we thought this should be reverted. Please read the previous conversations. Thanks.
