Starting today (I've had Beta for a few months), the scroller stopped working. I opened LogiOptions+ Beta and it showed a red button for my MX Master 3 labeled "Fix". I clicked it and it told me that I should restart "loginwindow". It turns out this is MacOS's login window, so I cannot restart this. I tried sudo kill on that process, but that logged me out. After logging in again, the scroller worked for about 10 minutes, then stopped again the next time I locked my screen.

See the following links where other users reported the same problem:

I tried switching back to the old Logi Options, but it said I had to use Options+ for Mx Master 3. Even after uninstalling Options+, it still said I had to use Options+, so I reinstalled Options+. After reinstalling Options+, I cannot add my device. When I click Add Device, it just sends me to the system Bluetooth settings, and the mouse is already listed there but doesn't show up in Options+. I tried removing my mouse from the System bluetooth devices list and then re-adding, but it still doesn't show up.

On the plus side, now that Options+ no longer shows my mouse, I can actually scroll again. I'm inclined to leave Options+ broken for now because it scrolling is working.

By the way, I have another Macbook Pro and it doesn't have this problem (same physical Mx Master 3 mouse, but I don't have the Options+ Beta version installed, only the old Logi Options).

How do I unsubscribe from the Beta? If it makes my mouse unusable like this, I would not to exit the Beta so I can use the old Options+ again.
