I previously muted the microphone using the MX Keys Mini (hardware button) and have since disconnected the keyboard. I am now unable to unmute the microphone without exiting the Logi Options+ app.

There are 2 UI elements showing that the microphone is muted on my Mac, but neither of them allow me to reenable the microphone (screenshot attached). This is a glaring UX bug and the functionality to reenable the microphone using software should be added ASAP.
