"Meeting will end soon" warnings not shown before 40 minute basic accout timeout

[robmOz]

I was recently in a meeting which was hosted by someone else which ended suddenly. I then saw the message "This free meeting has ended".

Previously I have always see a message warning me that the meeting will end soon eg 10 minutes, 5 minutes.

Just curious if anyone else experienced a basic (free) meeting ending without warnings?

Thanks

Same thing happened to me today and last week.  Where's the warning?
