Hi,
The only options under File>Export menu are for
Flows
MIDI
Tempo Track
How do export audio please? The manual says the option should be under that menu.

On the transition to OSX Catalina we once had the issue of missing audio export option, but it got solved already. So the first thing to try is, update your eLicenser Control Center to the latest version, you can download it from https://www.steinberg.net/en/company/technologies/elicenser.html
If that does not help, please check if there is an updated Dorico version for you available.
