Why is KuCoin not letting me buy?

Hello there, I'm facing an issue with KuCoin and I was wondering if you could help me out. I've been trying to make a purchase on the platform, but for some reason, I keep getting an error message that's preventing me from going through with the transaction. Is this a common issue with KuCoin? Is there something I'm missing or a step I might have skipped? I'd really appreciate any insight you could provide to help me resolve this issue. Thank you in advance!
