I just upgraded to Mojave 10.14.1 from High Sierra 10.13.x. I have been on Horizon 4.9 for a while. When I connect I get a black screen instead of the remote Windows screen. I hear Windows sounds and see the Windows spinner briefly like I always do when I connect, but the screen remains black.
I've seen posts that this was a problem with Horizon 4.8 but has been fixed in 4.9. But that is not true in my case.
Yes, it is working now. The remote desktop needed to be re-booted, then everything was fine.
Get this working? Other people here said updating to 4.9 worked for them. Wondering what else you needed to do to get yours working.
