This has only gotten worse. Now even Supplemental fonts can no longer be disabled. This is not okay. We should be able to have control over system fonts. Would love to have a sit down conversation with Apple to understand the reasoning here and how there can be a compromise to give use control over MacOS fonts.

Thanks to same post on Reddit, I was able to fix. You can try this on your Mac in the Terminal.app: defaults read com.apple.coreservices.useractivityd look for ClipboardSharingEnabled property in the output of the above command and if set to 0 do: defaults write com.apple.coreservices.useractivityd ClipboardSharingEnabled 1 I did not have ClipboardSharingEnabled as a property showing but the write got it working after a restart.

Glad I'm not the only one having the issue but some how I now have it fixed. I posted this Watch issue as well as Universal Clipboard not working https://developer.apple.com/forums/thread/727894 and for some reason, after getting that clipboard issue resolved (via help on Reddit), I was able to get the Watch working again by turning the unlock with Watch off and back on again. Don't see that the two would be related so maybe just turning it off and back on again repeatedly got it to work properly again?

The Keychain app still existed in Sequoia PB 1 for me but with this weeks update to PB 2, the app is now missing from my machine completely. I've looked in this CoreServices/Applications folder and it's not there. I realized it was gone when the dock icon was broken after update.
