Thanks for your answers!
On the devices with test accounts I see the website with “You are a tester” and I find the app in the store.
Now I added “verboseDebugOutput = true” to my code. The output in the developer account looks good. But in the test accounts there is this error:
02-07 18:31:44.275 32085 32100 I Corona : IAP Badger: loadProductsCallback 02-07 18:31:44.275 32085 32100 I Corona : Raw event data: 02-07 18:31:44.275 32085 32100 I Corona : table: 0x8a2c1980 { 02-07 18:31:44.275 32085 32100 I Corona : [errorString] =\> "Error refreshing inventory (querying owned items).

What does this mean?
