I am using Audacity 22.214.171.124 on Mac Mojave. I have noticed the Label Tracks are not working in this version. I highlight the section and can choose Label Track, which creates the track but without a label.
Any help or suggestions appreciated!
You highlight the section and use Edit>Labels>Add Label at Selection or its shortcut at Cmd+B to create a label
Tracks>Add New>Label Track just creates a new empty label track.
See this page in the Manual: https://manual.audacityteam.org/man/label_tracks.html
Amazing - thank you!
