Middle mouse panning - suddenly stopped working

Middle mouse panning in Adobe XD has always been the standard way I move about the canvas.

In the latest version of XD this has suddenly stopped working. It hasnt been replaced with a new function, just all of sudden it does nothing, and I'm having to use SPACE and left button to pan.

Sounds like I'm nitpicking, but honestly the muscle memory is so strong with this action, it's really slowing down my work.

Any ideas why this has been removed? will it be coming back?
