We're referring to the "Leave message for member via Audio & Online Banking" feature via Tool #70 Enter General Member Comments/Messages.
If you use Comment type 7 and choose message code 99 (the free-form text message), your custom message will be delivered to the Secure Message Center.
We do not warrant using any of the standard message codes also available via that tool to communicate via It's Me 247. (Those still work for audio response, of course.) Always be sure to choose code 99 and enter your own message content if you wish to send a message to your member via the new look for It's Me 247.
