Block rendering errors on the media page is new to me. I will look into it.

The reference language error should not be shown (I mean it’s not incorrect, but there is a “no expressions error” that should take precedence).

A video is coming :) I didn’t expect so much interest from a comment in this thread. If you get in touch, I can walk you through it personally, otherwise check back in a couple weeks and there will be a video overview.
