iOS Question iStore Debugmode dont find product

[kohlenbach]

Hi,
first in testflight all works fine. The tester can purchase and restore transactions.

In debug mode the log says : Product not found, Success=false

I created a sandbox user, logged out the App store in the settings.
In settings : developer account , I see SANDBOX-APPLE-ACCOUNT
the correct account.

The explicit ID I use for test is AD-HOC.

What I miss ?
