Jane.com meetings microphone stopped working in September

I have used jane.com via Safari for biweekly meetings for more than a year with no issues. I had no issues in a late August meeting. Effective September 15, my microphone will not work.

I allow the permissions when requested as usual, and the microphone works during the self-test. But, once the meeting connects, the other end cannot hear me.

Microsoft Teams in-browser does not experience this issue, the microphone works fine.

I suspect a recent update (there have been a couple) has broken something. Anyone have any ideas?
