2.3.0-beta.2

• Support syncing from 2nd generation 4k UltraFine to other displays (beta.1 could only detect 2nd gen 5k model).
• Started syncing to connected 2nd gen UltraFines again. Seems like most people like to rely on this app instead of the built-in ambient light sensor of the UltraFine.

To summarize:
If a built-in display is detected, the app will sync from the built-in display to all connected 1st and 2nd gen UltraFine displays.
If no built-in display is detected, the app will sync from the first 2nd gen UltraFine it finds to the other 1st and 2nd gen UltraFine displays.
