Hi Vera,
Great questions, here's the answers in-line:
1) When a product is pushed to a marketplace and ends or expires, am I supposed to relist through Shopseen or the venue where it was listed?
When a listing ends or expires, its deactivated and Shopseen is notified. Shopseen automatically re-activates the listing if quantities are greater than 0. If quantities are at 0, you'll need to update your quantity and then re-activate/re-list manually via Shopseen!
2) If products added to a venue are renewed on the venue does Shopseen pull the product into the inventory?
It should update within 3-5 minutes. Though, we'd recommend starting a Download Products process again just to be sure.
3) It is very difficult to tell which products are Not Listed on a venue because the sort feature only shows the ones that are. It is nearly impossible to find which ones have to be pushed to the venues where they are currently Not Listed. A small icon or the name of the venue where the product is active placed next to the product name on the product list would solve this problem. Otherwise one has to check product by product in the Stores tab. There has got to be a better way! Did I miss it?
Answered this in the other thread! We'll look into this :).
