The “We’re unable to send an SMS message to verify your mobile number” error may occur when your Amazon account is configured to use WhatsApp for verification instead of the required authentication method.

To resolve this issue and allow your orders to be processed and updated automatically in Easync, you need to disable WhatsApp verification in your Amazon account and configure Two-Factor Authentication (2FA) correctly.

Follow the steps below to resolve the issue.
