how do do a recording

Hey, @86176 –

You want to start a recording after the meeting is over?  Sorry, that’s not possible. 

Ray_Hardwood is correct, you can only do a recording during the meeting.

During the meeting, you only need to press 'Recording'.

Here is the article that I found regarding this concern:
