I'm trying to preview and publish a mission but it's just giving the pop up that says "Preparing Preview....." Then one never pops up.

Is there something wrong or is it my browser?

I have the same problem. Anyone have a resolution for this? I can't publish my scenario because it doesn't do anything on the preview pages.

I'm also experiencing this - looking at other threads it seems that it's just flakey as ****, try again later...

Update: I've been trying for 2 days, still doesn't work.
