Sonoma broke exposé?
Since upgrading my iMac 24" to macOS 14 Sonoma, exposé no longer works. This includes the Cmd-Tab and Shift-Cmd-Tab key sequences, as well as the F3 function button. Also broken are the similar Cmd-` and Shift-Cmd-` key sequences that shuffle through the open windows in the current application. This is making my life and, I'm sure, many others' lives, more difficult when trying to navigate in macOS.
Is there a fix for this, or does Apple have to release another update to patch this unforgivable failure of their s/w team to test new releases for breakage of existing features? (I worked in large-group s/w development & maintenance for a couple decades, so I have no pity for those who allowed this to occur.)
