I'm having the same issue. I listed 6 items thru eBay (with my own image hosting) about 2 days ago and they are not showing up in my store nor my store window. It's only showing items that are slate to end on Dec 15-16, and none of them which are due to end next week.
Could this be avoided if I listed thru Auctiva directly? And will those other 6 items ever show up in the store or are they done for?
