In-App Purchase Problem in SDKBOX, Cocos2d-x 2.2.6

Hi.

I am creating the quiz game using Cocos2d-x 2.2.6.
I have integrated the iap using sdkbox and it worked good.
But now it doesn’t work correctly.

When I click the iap button(to get coins), the popup message doesn’t appear to login the apple account.
And it logs “INF: SDKBox IAP: Processing a previous payment”.

Please let me know if anyone has solution.
Thanks

Which version of sdkbox do you integrated with?

Thanks for your reply.

The version is 1.5.0.3.

Can you try upgrading to 1.5.3? we fixed couple issue since 1.5.0

yes. I tried.
But not working yet.

How can I fix it?

Is this still not working for you? I have heard that the Apple IAP servers can sometimes go down, for days at a time.

Is it possible for us to look at your code? or a sample code?

Here is the sample I’m using to test SDKBOX iap, can you double check and see if the integration is the same?
