I'm trying to migrate, but when I push the "Send to marketplace" button, I get this message: "Marketplace initialization failed. Initialization with the marketplace failed because of a system or network error. Try again later" Well, I tried later and that message appeared again and again... I don't know what's wrong, please, help me with this. And I have a question, will magic boxes stop working anytime soon??? or we can keep it and still selling through it??
