Screen freezes after going to waiting room

Prior to entering the waiting room, there is movement of my image on the small window on the right of my screen. When I welcome my patient, my image either freezes immediately or after a very few seconds. I have checked

the settings and they look right. I have refreshed the browser but this doesnt help. Any assistance would be greatly appreciated.

I have had this as well. I think it just has to do with internet connectivity. Would be good to hear from support
