I see this seems to be compatible with “Boxes with Subcategories”, and I have that working on my installation, however as soon as I enable the air theme the category previews disappear. Is there a way to get this working with that theme? Thank you!
I’ve started doing some debugging and I can see that it is entering this block and should be adding the previewData to render, but it doesn’t even show up in the output HTML on the page.
