I got the authoring tool and framework up and running on AWS the other day and am now working on a course to learn the ins and outs of Adapt. In the authoring tool, I'm able to upload assets, use them in the course, but the preview of the image isn't showing up. The images I've been using are somewhat random, just to test, are there specific dimension constraints I should know about or is this something else?
I didn't find the right solution from the internet.
