How do I edit front matter now after the upgrade?

What I’m trying to do

I have a template for front-matter. One of them contains JSON. I need to edit it each time I publish. But it seems uneditable.

Things I have tried

Clicking everywhere.

Switch to Source mode or change the Display mode for the Properties view UI (Live Preview and Reading Views):

It’s in “edit” mode right now. I don’t see a way to shift the properties to source mode, but let me check your link.

Ah okay I switched it to “source” mode, let’s see if I can use it, it displays in the more familiar “YAML” which I like, not sure what it means for the markdown. Thanks.

the markdown is the same as always, in normal YAML format. It’s just changing how that markdown is displayed.
