Why can't I buy coins on Coinbase Wallet?

Hey there, I'm having some trouble buying coins on Coinbase Wallet. I've tried everything, but it just won't let me go through with the purchase. Is there a specific reason why I'm facing this issue? Could it be something to do with my account settings, or maybe there's a technical issue on Coinbase Wallet's side? I'd really appreciate it if you could help me out with this. Thanks in advance!
