I have same issue. There is no problem on my device and simulator. But Apple Tester takes this error on review. So my app rejected. "Error 23: There is an issue with your configuration. Check the underlying error for more details."

Same here. My app approved and listing in market but my in app purchases not working. This is so bad.

I’ve already submitted an appeal and also spoke with the App Review team over the phone. Unfortunately, both the appeal and the call ended with the exact same response, without a proper review of the actual app.
