Dropbox Embedded not working with /scl links.

Our site uses the dropbox embedder to display shared folder content with our users. The problem we're having is that the newer shared links that are created with a /scl url prefix won't work with the embedder. The older shared links created with /sh prefix work fine however. When a user with the /scl style link tries to view the embedder they are prompted to 'request access' which then sends us an email and notification that '<name> is requesting access.'  I've compared the meta data between the working and non-working links and don't see any real difference that would explain the behavior. I've also tested the non-working links in an incognito window to see if navigating directly to the link works (vs using the embeddder) and they work fine.  Is this a known issue? Anything else I should explore to try to get the embedder to work for these links? Thanks!
