I just attempted it and it was failing due to emotion-js having issues with the app directory. I am using MUI in a custom component if that makes any difference, but I followed the tips to try to force it to work and was still getting issues due to builder.io’s dependency on emotion. I wasn’t able to resolve it, so I’m reverting back to Next 12 for now.
I’ve been trying to get Builder to work with Next 13, but I see weird issues, such as losing my layout when I use the browser’s back button, or having every page render what should have been the previous page when using @builder/sdk instead of @builder/react to fetch a page and pass it directly to <BuilderComponent model='page' page={page} /> on the server.
