Why can't I swap on Trader Joe?

I've been trying to swap tokens on Trader Joe, but for some reason, I can't seem to get it to work. I've made sure I have enough of the tokens I want to swap, and I've checked that the network isn't congested. Could you help me understand why I'm unable to complete the swap? Is there a specific issue with my wallet, or is it something else entirely? I'd really appreciate any insight you can provide.
