Allow participants to unmute themselves - option not showing in Settings

Suddenly, people can no longer unmute themselves in a meeting.  (It's SO aggravating and unprofessional when Zoom autocratically changes settings without even warning, so we get in a meeting and it's not working as expected! 🤨)

I found this answer but the setting option doesn't exist...

"This setting (Automatically mute all participants when they join the meeting) will disable all participants’ audio when they first join the meeting, i.e. they will be able to unmute themselves after joining.
"Afterwards, the host or co-host can mute all participants that are already in the meeting, as well as new participants joining the meeting. 

1. Click Participants
    located in the meeting controls.

2. Click Mute All to mute all current and new participants.

3. (Optional) Check Allow participants to unmute themselves if you would like participants to be able to unmute at any time during the meeting."

    

I can't find  Participants tab in the first place, but i do see this...

"Mute all participants when they join a meeting
