Nothing works with update 0.90.
No per application customization.
Even global settings do not work any more. Both for MX Keys and MX Master 3.
The menu applet icon is not showing. It is there but invisible and doing nothing.
The login window from firefox can not start the options+ app.

The old options app redirects everything to logi options+ app even after removing all traces of the latter from system.
How can I uninstall completely the Plus app and go back to options? I do not wqant any beta any more.
Or how can I install previous version of options+ that worked?
Again EVERYTHING IS BROKEN - in 0.90 beta. I am in macOS big Sur connected by usb unifying conector
