Samsung TV (UN58RU7100) won't connect to Airplay OSX (10.14.6)

[gh0stwhit3]

I have Samsung Smart TV 2019 model (UN58RU7100) with latest software (1351.4) and having problem with Airplay. The TV won't show anything (blank) yet it's connected with my Mac. I'm using latest OSX (10.14.6). I tried to reset the TV, turn it off and on, reconnect and nothing is happening. Help pls?

I am also experiencing this problem. Or when it does connect, the connection is so unstable that it only lasts a brief time. 

#Samsung tech help, how do we resolve, please? I have a Samsung UHD TV 6 Series NU6950.
