Thanks for your note. I am trying to Auth a developer, I have their key, but when I visit User Permission screen, I do not see the MWS option to Authorize a Developer. The developer showed me the screen to paste their code, but my account does not show that option.
Do you know why that might be? We do have a Proessional Seller Central account.
When I try to add MWS I get a “Function not available while in Beta Mode” error… ?
