I update fairly regularly, but not done it for a while. I will try it and see what happens

It has only started in the past couple of days and the update is only 0.18mb

Just done the update and still the warning. Its not stopping me list. But what does it mean "seller profiles will soon be mandatory"?. What's a seller profile?

I have no idea what a seller profile is.

I don't have anything like your volume of sales, but I do have a store and TRS, and like I said, I don't get that warning. If it was just today I would suspect it to be Friday maintenance day glitches, but you said it's been happening longer than that.

Also interesed to know what this means.. We upload about 50-100 items a week, and get the same message for atleast a month now. I update program weekly...

Error message:

Warning 1 of 1

Seller Profiles will soon be mandatory while creating a new listing for business policies opted in sellers.

Seller Profiles will soon be mandatory while creating a new listing. Support for Legacy Shipping, Payment and Returns fields will be going away for business policies opted in sellers.

 No one seems to know unfortunately.

To my understanding, that's saying if you are opted into Business Policies, you will have to create listings using Business Policies, rather than filling out separate / independet Payment, Postage and return fields (or using a template with those fields filled in already).
