@davidelliott I suppose they are all away for Christmas holidays. I try to give you a reply since I already discussed this point in the forum.
It is a bug of relisting that I met almost every time I manually relist. Most of the time that advice is wrong since there is not actually an already listed identical one. Next time you see it, let’s search into ebay shop that listing. I guess you will find nothing. In my opinion (probably wrong, but that’s the only idea I had…), this warning is due to the lack of updating of your listings. If you set “updating orders” to “never” in GS preferences, probably that listings was not already updated and GS thought it was still active, while it ended and had to be relisting. I suppose that inactive listing was an ended one that you restarted, am I wrong?
Also this point was already discusses: Listing while GS is relisting: CANNOT WAIT HOURS . I know there is somewhere another thread concerning what you said (stopping listings). The matter is the same, if GS is relisting, it does not prioritize other actions, stopping or listing is the same. Next time you cannot stop a listing, press cmd-alt-zero, you will see GS is relisting or “sending images…”. In that case, if you stop a listing within GS while it is relisting, it will take a while before seeing the dark icon (expired), however GS stops the listing almost immediately (click on “see on the web”), it just requires more time to change the icon during relisting.
That message says Gs is working (probably relisting), so DO NOT stop GS if it is relisting, it will give you much troubles (tried…). Press cmd-alt-zero and make sure it is not resisting before force quitting. @ilja in my opinion it would be useful (for those who do not know cmd-alt-zero) to add running activities in the “closing panel”, don’t you think?
P.S. I just realized you said
I have to partially change what I said. Open preferences and check in “order” what you set as updating time. It’s obvious that Gs updates the orders as soon as it is opened and after the time you select (5 min or 2 hours). Anyway, avoid stopping listings from ebay, if you can… it’s better if you do it from GS
