Problems with Affinity Designer purchase after test version

[Antje]

Hello! I downloaded the Affinity Designer test version about 14 days ago. The test license expired a few days ago. 
Today I purchased the full version in the App Store. When I open the app it shows that my test version has expired and that I need to insert the product key to proceed. I didn't receive the product key because I bought the full version in the App store. What can I do?
Thanks in advance.

Hi Antje,
Welcome to Affinity Forums
The trial is still being launched. Uninstall the trial, restart the system. This should fix the issue.

Thank you so much! I was able to install the full version.
I was wondering where I can download the Grade UI-Kit? Can you tell me?
