InAppPurchase not working in app which is downloaded from AppStore!

My in-app pu开发者_高级运维rchase status shows "ready for sale" in itunes and i downloaded my app from the appStore...

But the store returning 0 products...Not possible to purchase any items.. What might be the problem? Any Idea?

app is released on 18-Apr-2011 to canada store only.... Is it take time?

Thanks in advance.

please check bundle identifier. it may be change or may be some space at the end. because if store return 0 product means there is no product for the given bundle identifier.

Thanks .

I don't know what is the reason... but the apple guys took 24 hours to enable inApp-purchase now it is working fine...
App is released on 18-Apr-2011 and inApp purchase started working from 19-Apr-2011...

I faced exactly the same scenerion in my app..the apple wasnt verify the product id during the first 24 hrs and so it was giving invalid product id error which in turn was generating the "in-app purchase failed" error..And then after 24 hrs (may b a little earlier than that) the in app purchase started working perfectly fine...

In-App in my app was released on 20th april..Kept on giving the error... In App started working fine on 21st April...!
