Can't set sandbox account type to business
I'm trying to set up my trading API. It all worked well on US sandbox, but now I switched to UK, because I want to sell in GBP. I'm getting an error: "You are unable to list items, because you have not confirmed whether your account is for personal or business use." But when I try to change it in my settings I get "Http/1.1 Service Unavailable" Can you change it to business for testuser_brandsguru24uk2?
