Metronome while MIDI recording

I want to enter notes with MIDI input in Dorico 4: When I start a recording, I get a count-in from the metronome but the metronome sound stops after, only the red caret is moving. Can I listen to the click while inputting notes via MIDI?

You should certainly continue to hear the metronome click during recording. Does this problem affect all projects, or just one? Have you overridden the metronome sound in Play mode, or are you using the default metronome click sound?
