license number

Hello there,
I bought iStopMotion 3.7 in the App Store, unfortunately, they can not connect to the iPod or iPhone.
I would like to download and install the Beta Version 3.8 and activate the license number. As I have but it bought in the App Store, I have not received a license number. What can I do? Why I’m at a disadvantage because I bought it on the App Store?
Thanks and Greetings

Hi Sophie!

To test iStopMotion beta you either need a download license or you request a demo license (which can be done within the download app itself). I am sorry, but we don’t get any customer data from Apple.
