I’ve had this problem for a long time, have tried several different browsers, cleared cache, etc. no luck.
But did solve the problem a different way. I no longer click on any msn videos, instead if I’m truly interested, I search the title on YouTube or Bing and am generally able to find and watch.
I figured if they don’t want to provide legit support they don’t care if we actually watch on their platform.
Good luck everyone
