Just started using linnworks and i'm very impressed so far. I've managed to link all of my SKUs from Ebay, Etsy and Amazon and can see orders coming in etc.
However my stock levels don't seem to be getting auto updated on Etsy when I sell on ebay/amazon. I checked on Etsy and get the following message.
Is there a known issue that stock doesn't get updated on Etsy or can anyone advise a way I might be able to fix this?
