Yes and no.
It took a couple of weeks before I could follow the instructions to move listings to dotCOM.
(Why don't programmers hire a technologically inept idiot to try new programs? It would save so much trouble. And the ad would probably go viral.)
Then it uploaded every attempted listing.
Including duplicates.
So then I went through about a thousand listings and manually deleted about 300.
Fortunately, I am a night person and live on Vancouver Island, so much of this happened around 2am EDT.
BTW, to check for duplicate listings, click on your Active titles and put them in alphabetical order.
Duplicates will be easier to spot that way.
