Cannot preview

So I've been trying to use the Preview/Editor button, and it the preview only shows up blank, any insights?

It's turned on in each code challenge so if you find another one that you think needs the preview and doesn't seem to have it, let me know!

Oops! I was missing a flag for the preview. It's fixed and available now.

Heyo, I'm not sure what a flag is in this case, but it looks like the preview is only fixed for me in the Python Collections course. Python Basics, and I might guess other courses' previews are also similarly blank. Thanks
