Reply to Nonostanovich since I previously tested this and it DID NOT work. SO retesting now at build 10.0.10586.36
Test 1 with Edge set to the default (mobile) browser. Start hangouts.google.com. Contacts are displayed so that I am logged on. This step takes over 30 seconds. Press on a person to start a conversation: NOTHING HAPPENS. Get somebody to send me a message whilst browser if foreground: WORKS. HOWEVER only first line of message is received. Rest is lost because no popup is displayed. Also cannot send a message since cannot initiate person popup.
NEXT: set Edge brower on W10M to Desktop mode. Start hangouts.google.com. Press on person to start conversation. I can see the whole text of a message sent to me. FIRST time I can reply to message. However after that I can't get input focus on send message entry box, PLUS from a standing start I still cannot initiate a message.
NEXT: in dekstop mode keep browser on hangouts.google.com and put to background, look at start menu. Somebody sends you a message. NOTHING! Navigate back to browser and first line of message shown.
So now after over 15 minutes, with 2 people, testing both ways for verification, of testing on a 1-10 goodness scale this is a 1 at best. To say that this is a workable solution even in a dire emergencies is a joke. I'll repeat that /word on the street/ is that Google is at fault for not making any sort of effort to make an app. Should this be true shame on Google.
