Moonpay can’t sell bitcoin

Downloaded moonpay, on the app there was no verification process. So I bought some bitcoin but now when I try to sell the bitcoin it says “missing balance account. You need to create a moonpay balance account to continue” but I’ve searched literally everywhere there is nothing on the app that says anything about a balance account and how to get one? any1 know what to do?

I’ve even searched online but can’t find anything :-/ not sure if I’m just being dumb but this is very frustrating

Why would they let me buy bitcoin if I can’t even sell it 😭
