Unable to turn on closed captions on iMac

[YokaV]

While I am able to see closed captions in some meetings, I am unable to turn them on in other meetings. I have gone to Accessibility in Settings, but  CC simply would not appear at the bottom of the screen. They did not turn on when the other member present initiated the call, nor when I initiated the call. I did get as far as seeing the sample of a caption, and I turned on "enable." I hope someone can guide me to a solution.

I have same issue: When I start a new meeting and try to enable Live transcription (by clicking on the "enable" button), it does nothing. I checked in my advanced meeting settings and Transcription is enabled. I suspect this is a bug. I am using Version: 6.4.1 (51520)
