I attended a webinar a while back on this subject. I believe it covered the MDS and what your options are. I don't remember the answer, too many beers ago.

I Tried to use it on Microsoft edge and it didn't work, then I switched to Google Chrome and it worked.
Also keep in mind this webinar I believe is hosted by summit, so they're opinions could have some bias, I'm not sure.
