Fast Switching kills the feature?

I have two Macs each have 2 accounts (with 2 Apple IDs), local names, etc. are identical.

If I Fast switch on each to the second user, Universal Control stops working. The only fix is to log out and log back in as the second ID. Cumbersome at a minimum using a combination of Screen Sharing since I have ONLY one Keyboard / Mouse in the Office.

I explicitly turned on Auto-Reconnect. All works OK as long as I am NOT signed in to another account on the either Mac.

You have to be logged in to the same AppleID on both devices for Universal Control

2 Apple IDs seems to be problematic...

Use a single keyboard and mouse between Mac and iPad

The current stable release of Monterey including bug fixes, is macOS 12.4

Switching users may also have changed the Apple ID you used for iCloud. However, Universal Control will only work if your devices are signed in to the same Apple ID.
