Coinbase Coin Trading and Transfer Issues - Errors Persisted for Seven Days

I’ve been unable to trade or send coins to other addresses on Coinbase for the past week. Every time I try, I encounter an error that prevents any transactions from going through. I’ve tried multiple times, but nothing seems to work, and the error message just says “sending error.”

This situation is incredibly frustrating, especially when your advertisements promise a smooth experience, but the reality has been quite the opposite. I need urgent assistance to resolve this issue so I can use my account properly again. Please address this matter promptly. Thank you!
