3-Way Wiring Question and Question re: Leviton Aux (dd00r-dl)

I’m not sure. My first inclination was to say the Aux can’t tell the Inovelli to send a scene, but the 1.54 firmware update on the dimmer fixed “Aux Switch Not Causing Scenes to be Sent”, but I’m not sure what that means.

I don’t have anything set up in that configuration so hopefully someone else can jump in and answer.

EDIT: See this regarding scenes from an Aux with a dimmer:
