Receive email notification when person joins personal meeting room and host isn't/we aren't in there yet

This helps let us (team of 5 here in our small business office!) know and is a good reminder if we get busy - that someone is ready for our meeting! We used to get an email reminder when someone joins our personal meeting room if we weren't in there. As of today, that no longer happens because, according to the chat rep, our account has been changed to the new version and that's not a feature. It is a lifesaver! We need that back if possible!
