I've scheduled five listings for later today and none of the descriptions show up if I look at them via the Scheduled Listings page.
However, if I preview them through the Saved Listings page I can see them (as Kevin suggested above). Does this mean I can feel confident about continuing to schedule more listings today?
By the way, I notice that the old editor is back but I still had the disappearing problem when I used it (I tried only once -- maybe it was right as it was being switched back, I don't know).
That's using Firefox. If I open up IE (which I hate to do) the editor doesn't seem to work.
