Still haven't been able to get this working and wanted to provide a bit more detail.
In my application.js I do have //= require trix and I can see the file in the head of the page; however, it does not look like the same file that appears on trix-editor.org. It seems mostly the same, but if I do a search in the files for the keyword "config" I get 47 matches in the file on my app and 56 in the file on trix-editor.org.
Could this be a versioning issue?
Thanks for the quick reply.
I'm pretty certain it is importing, I see the link in the head.
