We have been battling with exactly the same issue for some time now and I am surprised that this hasn't attracted more attention. Neto says that this is to help avoid overselling items. But, you can list all of your stock on your website and on one other platform, so that makes no sense at all. It is obviously a glitch in Neto's system that needs to be addressed because as it stands, listing on multiple platforms, which is something we pay for and Neto boasts about, is totally unworkable 🤷♂️
