Why can't i buy from Coinbase?

I'm curious, why am I unable to make a purchase from Coinbase? Is there a specific issue with my account, or is there a general restriction in place? Could it be related to my location, or perhaps there's a temporary hold on transactions? I'm eager to understand the reason behind this and find a solution so I can continue investing in cryptocurrency through this platform. Could you please provide some insight into why I'm unable to buy from Coinbase?
