SOLVED IN OTHER THREAD
See this post (in the general channel).
I’m hoping for some help - code components that I have registerd are showing up in plasmic studio & I can also see them when I preview from plasmic studio, however they are missing when I view localhost:3000 or publish to vercel.
I’m using nextjs pages router, plasmic loader method
My app host is currently set to http://localhost:3000/plasmic-host
