I get this same message when I try to enroll any of my current listings over to FBA, I have tried many times with various of my listings both unbranded and branded and nothing works.

I have spent weeks speaking to chat who don't seem to know what the problem is, they pass the case on to specialists who then don't seem to reply.

I'm brand registered and keep getting recommendations to list my products with FBA for more turnover. I have tried letting Amazon auto-generate their own SKU and I have also tried entering my own.. No matter what I do I get this error message (see screenshot) and can't progress any further?

Does anyone have any clue why this keeps happening? Am i perhaps not fully set up at account level to do FBA or is it a product issue?

Thanks

Dave
