Homelife Camera life feed causes error on Galaxy J&

Recently purchased a Samsung Galaxy J7 android phone (Verizon).  Downloaded Cox Homelife app.  I can sign in OK and see the camera still feed, but when I tap the scene to get the live feed I get "kicked out" of the application - - and it closes.  I can do all other functions with homelife including viewing the camera still pictures that are refreshed every 10 seconds, or so.  My android system is 7.1.1., I believe.  Can anybody help?
