On the MX Keys Mini keyboard (non-Mac edition), with the keyboard set to use F1-12 keys instead of special functions, the volume up key does not work as intended. My best guess is because the key is not a proper F-key (it's Insert), the switching behaviour isn't properly applying. This effectively means regardless if you have the option to swap F keys with special functions enabled or not, volume up is always just the Insert key (no FN). With the swap enabled, the behaviour as compared to volume down is noticeably inconsistent / annoying (hold FN for volume down, don't hold it down for volume up). This is the latest Options+ running on MacOS Sonoma 14.5. Thank you!
