Brightness are linked in macOS Sequoia beta 2

[dangh]

I just upgraded to beta 2 and noticed the issue. I'm not sure it because of the beta or because I changed some configuration recently. But I have tweaking bunch of settings but still have this issue.

To describe my issue, I have two monitors apart from my MBP (1). One is a desktop monitor (2), another one is a portable monitor (3). Previously I can change brightness of 3 monitors separately. But now:

• Change the desktop monitor (2) brightness, it works as expected.
• Change the portable monitor (3) brightness, nothing changed.
• Change the MBP (1) brightness, it change the desktop monitor (2) and portable monitor (3) brightness as well. I have to change the desktop monitor (2) brightness again.

Is there anyone having the same issue?

Is this something new with beta2 and worked with beta1? If you reset BetterDisplay's settings completely, do you still have this issue?

Can you give some more info about the config, displays, connections, app version?

(Note: the app has various brightness synchronization features, I assume you did not turn any of those on).
