Just to add to what Chris said, if there is something you can't configure, drop us a support ticket or a message on our discord server and we'll point you in the right direction.
I have checked over your VA and the only features not currently available are the batch importers system, which will become available at 20:44z tomorrow, along with the ability to start a subscription, but there is nothing that you can't setup and configure on your VA that I can see. You dont need to start a subscription to use the importers.
We have intentionally made it so you have access to everything in trial so you can fully setup and trial our platform yourself, without restrictions, so you know exactly what you're getting before subscribing.
(You also don't have a pilot registration link yet which is the only part that requires a subscription, but there's still plenty to configure before you start having pilots join you)
