After I login, my first Command-\ to fill in a password fails (meaning the window opens but never requests a password... the fingerprint image goes from bold to faded). After a pause I have to enter Command-\ again to get a login prompt. This is in Chrome "Version 83.0.4103.116 (Official Build) (64-bit)" (though may be other browsers... don't remember), on 2018 Macbook Air.
