content: Have been using this for work. I have the app installed on my chromebook. I have a new glitch where the end call button disappears unless I am using full screen which is a problem when Im doing voice only and need the rest of my screen for something else. The call will not hang up if I just exit out of the app entirely. In addition I have not been able to type messages into the chat and end up having to pull up the IOS app on my phone.
