Interesting! So it can work, that’s awesome.
Just to make sure then, right now I have one site that’s using the child theme and I’ve been building all of the custom fields on that one. So what I would do is start a new site with parent theme activated, import the parent theme fields there, sync it with JSON, then delete the parent theme fields on the child theme site so that they only show up from the JSON?
As always, thanks so much John!
