needing to quit and restart Musescore to see Chord symbol Text style changes
I'm using version 3.02.20666, rev. 8ca4d2c on Mac. I'll go into Format - Style - Text Styles - Chord Symbol and do some changes to the chord symbol text style, and press OK. Changes aren't visually updated unless I quit Musescore and open it up again. I've only tested this in Page View.
