Unable to play streaming videos

Hey there,

So using the UWP app I seem to be having issues playing online straming videos.
It’s been happening since about beta 4, and I was hoping it would be fixed but so far no joy…

Just trying to to use the youtube or other video plugins, I get the following error in the log:

Code:

Any ideas?
