Performance of TVM is poor and unreliable

Each time I connect to use 'meeting' (which I admit I've only been trying for a few months, having always use straight TV + phone, FaceTime or Skype) it usually ends up with having to cancel it and connect again because either the other party (having accepted the invitation) doesn't appear in the participants list or one of us has no audio (despite toggling the mic several times).

If that wasn't bad enough the latency is very poor. I thought it might be one end or the other of my regular connections but I have tired out a *FREE* product called Zoom and it is blisteringly fast (almost no latency), connects first time and is as stable as a rock.

What am I paying the subscription licence for TV for? I must be mad!
