Hello, I just noticed your message, sorry.
The trick worked for me on an apple computer (macbook air), with a standard meeting,
I never used recurrent or breakout meeting.
Anyway, if you try the “hot swap” method just BE SURE that you do it AFTER you stopped recording your fake meeting but BEFORE you click “end meeting”.
You’ll find a new folder with today date with a file inside name “double_click_convert file”, (that you must swap with your unconverted file)… If you find an already converted file (like name.mp4) you can’t do the trick.
If it didn’t work probably I cant help. I suggest that you write back here exactly why it doesn’t work, tell the entire story…
