We have the free plan with 3 licenses. We have only used one of the licenses to develop the Pi into an IoT kiosk. Now we want to test it out in the public and generate feedback on the interface. Is there a way to remove the white box that shows that it is an evaluation version? We want to use our two remaining licenses on an A/B test to determine user preferences. To do so, the system will need to remain on for days at a time. Thank you.
