I would to test some Apps also the App Purchase Sandbox feature, but it’s don’t work for me and I would to know how it works and what I need for it.
I get this message “You are currently not entitled to in-app purchases to do in the sandbox. This Apple ID does not have the Necessary permission to in-app to make purchases. you can Account Permissions in iTunes Change connect. [Environment: Sandbox]”
If I go to iTunes Connect the page don’t open also I can’t log into App connect. Maybe some can put me in his Sandbox tester account. I can also pay for it or do something else
