You've included new integration with the release of PRO 3.0, exactly what I've been looking for, but it looks like it's only a trial version? It doesn't fully work when installed.
It looks like their booking form only works on PRO license, which mean no one would be able to book any event.
I've missed "Tickets" button. Separate to Event fee field and other time related settings, you need to add tickets, and repeat cost, time etc. And then registration form will show up.
