All my products were selling well on Amazon and they suddenly decided to revoke BuyBox for ALL my products.

I can understand losing BuyBox for 2-3 products but ALL!!

I have raised multiple support tickets but Amazon keeps giving the same information all the time.

I already checked the performance of account, account health is good, delivery is FBA, no A/Z claims, no bad customer experience, we even reduced the prices.

Does anyone know what I can do here?
