Cant Send To Recipient?

At times, you may encounter a pop-up message in the Mass Messenger feature indicating an error when attempting to send a message to a specific recipient.

To investigate the issue, you will need to manually click the list icon, "eye" icon and then click the "Continue" button inside Facebook Messenger.

This issue typically arises due to a Facebook bug where clicking the End-to-End encryption "Continue" button redirects users to an error page.

Normally, clicking the button should automatically open the Messenger chat for your message to be sent. However, since this bug occurs on Facebook's end, there is currently no fix for it.

The best course of action is to remove the person from the sending list to resume sending to the remaining list.
