Hi Josh,
thanks for your answer.
Here are some screenshots:

Plugin list – both free and pro are installed, activated and have the same version.

Missing license tab on settings page.

Recurring events.
As you can see the website is German but I hope the screenshots help anyway.
As it seems to work properly for me there shouldn’t be a problem from my side. I just want to ensure that the plugin / pro features don’t stop working suddenly. For you, it’s probably interesting as I didn’t need the license key I bought.
Let me know if I can help you somehow.
BR Dominik
