Sharescreen via Airplay is not working in Zoom: the "Zoom-Device Name" option disappeared

[falinwongchem]

The symptoms:

- Sharescreen green button -> Advanced -> Share via Airplay -> no "Zoom-Device Name" option appeared on iPhone/iPad

- "Device Name" as an Airplay option exist, which means I can Airplay iPhone/iPad to my device;
    just no "Zoom-Device Name" option, so I cant Airplay to Zoom

- The only solution I found in previous discussion does not work for me (reference post)

   If i follow "system preferences—sharing—turn off AirPlay Receiver", my "Device Name" option will disappear.

   And the option comes back when I turn on AirPlay Receiver.

- Sharescreen in Zoom via cable works. That's how I survive my work now.

   But I want to share wirelessly.

- My MacBook Air does not have this issue, but my Mac Mini does, and I updated their MacOS and Zoom software at the same time.

- All devices are using the same network, up-to-date softwares, Zoom reinstalled multiple times, devices restarted multiple times already

Would be great if anyone could help.

Thanks.

Got the solution, post it here for everyone:

Privacy & Security -> Local Network -> turn on Zoom Workplace Airhost

typically for those who used to turn off all the Local Network authorization
