I fear I installed the plugin incorrectly (did it manually instead of through the sketchucation extension), but regardless, I have no way of manually releasing seats through my account, despite documentation stating that a user should have the ability.
All devices needs Sketchucation Tools 4.3.1. If you activated using an earlier version then you need to update that device/s to the latest for online seat management at https://sketchucation.com/webshop/my-licences.php
