Air play from Mac to Samsung TV does not work, ok when using iPhone
I've tried to use Air Play in my Mac to use Samsung TV as a bigger screen. It looks like Mac and Samsung find each other (asks password), but after a while connection goes away and Mac never shows up in Samsung.
When using my iPhone Air Play works fine with the same TV. Somehow I expect that the problem is in Mac's system preferences, access rights but I've not find the right parameter.
Catalina 10.15.6. in Mac BookPro11,1
Samsung AipPlay version 17.24.6
