This is driving me absolutely mad!
I too have the same issue. Last week it even got to the point that I reinstalled windows and it solved the problem for one day.
Here is it working on Thursday (looking great):
Now I’ve just tried to use zwift tonight and I’m back to the same issue.
See here for a youtube link showing the issue.
I can see other riders chat, it says everyone is online, I can join them etc, I just cant see them.
The wierd thing is as well that as I’m the only rider on the course I get the sprint, KOM and orange jersey!
Please please get this sorted zwift. Its obviously a problem at your end. I have tried disabling firewall, anti virus etc. I’ve got 40MB DL / 20MB Upload broadband…my connection is fine with all other apps.
Please look into this.
