  • Have you ever used desktop Chrome to simulate a mobile device? It is possible that you have the mobile version of the configuration cached. The cache headers for the editor's configuration do not consider user agent (since a browser's user agent string doesn't change with regard to what is being reviewed outside of development). A cache-bypass in Chrome (or manually expiring the cache) should resolve the issue.
