LOL - I don't think theres a button to reverse zoom.
Just to be clear you're using the Right Zoom Wheel on the the RC?
(pushing it to the left or right should shange the zoom) Also on DJI go 4 theres a Zoom SLider available -
I don't like the zoom wheel arrangement either. Should be 'Push up" to zoom out and "Pull Down" to pull back in. As Rockowe points out.. It can't be reversed.
