Sorry for the frustration. If you request a new verification code, the previous code becomes invalid, so please avoid clicking “Send Code” repeatedly. The 30s is only the resend countdown, not the code’s validity period. Each code remains valid for 30 minutes. Please use the latest code you receive.
