Unfortunately, as great as Sessions looks, it's simply unreliable. I have experienced way too many times where a client or guest tries to come onto my Sessions call and although they are connected, you cannot see them on screen or them... they can hear you and see you but that's simply not the point of a video meeting. This has happened with multiple clients on multiple days in multiples different Sessions "rooms". The only answer I have found is to give them my old Zoom link and everything works great.
