I have read so many questions around with the same error, same of them are old, and some of them very old. It's unfortunate that this issue seems to be around for so long, and not attention for eBay has been giving on this for so long. Anyhow.
It looks like a have all the credentials and permissions set for my user, but i still get:
errorId: 25018 message: Incomplete account information. Before you can list this item we need some additional information to create a seller's account
I gave up using the sandbox long ago, therefore, I am getting this error in production.
Has anyone faced the same issue recently, and more import, has anyone worked around and was able to publish an offer?
