When I try to create an inventory group I get this message:
"The following SKU is already a member of another group. SKU: SL5596 groupId: VAR9"
I tried deleting or querying for the groupId VAR9 or the item SL5596, but both yield just a 404 error.
For example: https://api.ebay.com/sell/inventory/v1/inventory_item_group/VAR9 returns "404 not found" . (Using the API Explorer - and a double check with another group returned a 200 for that, so I am quite sure I am correctly authenticated and using the correct live account)
So how to delete a group that seems to be "undead" - deleted but at the same time still there ?!?
