I've just configured our site to use AWS S3 as a CDN for the images directory and contents, and so far it works well with basic articles in testing; however, any custom fields used to populate our pages in Yootheme Builder only see the native images directory, not the S3 directory. This is particularly noticeable with repeatable fields and using Media as the selected element.
Am I missing something here? Are custom fields excluded from using the JCE media manager/S3 plugin? That's kind of a deal-breaker if so.
