Hey @hi999, how are you accessing the recording file? Have you tried to manually convert the local recording files?
You can attempt the following:
-Visit the location where the local recording files are stored, the default path would be: ~/Documents/Zoom -Find the file double click to convert and double click it to convert -If the “double click to convert” file is not working, with this trick try making a new “meeting”, with only yourself. Start a recording, then after a few seconds stop it, but don't end the meeting. In a folder inside documents/zoom/ named with date/time, you can locate a new “double click to convert” file. Swap it with the file you need to convert, then stop the meeting.
Looking forward to your response and let me know if this helps!
