So tried Live Chat for the third time today and finally the issue seemed to resolve itself - not sure if it was something the LC person did or it just worked itself out. Then a couple of hours later the problem returned. I am almost ready to give up.

On another note - is there any way a SINGLE item can be placed in a store category? Whenever I try to do this, it just opens up the window you get when you go to list a new item. There is nowhere to choose a store category - any way round this?
