Why did the function key shortcuts in Pages, for text paragraph styles, just completely stopped working on in macOS?

On every single Mac I have (whether 2015 MBP with 12.6.1, or brand new latest Macs w/ Ventura), The fn key shortcuts, for text styles, no longer works in Pages. What could this possibly be? When you click one of the fn keys, it simply "beeps" and nothing happens. Is anyone else experiencing this? To test, open Pages and try a function key in any Pages doc. # Update - fixed? I recently bought a - M2 2022 MacBookAir - Currently with Ventura 13.0.1 - The latest Pages (actually 12.0 7033.0.134) Fortunately they do seem to have resolved the problem, it now works normally. Hope it helps someone.
