I agree with the other posters here. Samsung's decision not to put the app on earlier Smart TVs is nothing more than a strongarm tactic to get the consumer to buy another TV. Sorry, but if I do purchase a new TV, it won't be a Samsung. This no Disney nonsense is a real turn-off.
I have a js8500 from 2015. I too am very disappointed with Samsung. As a result I will avoid Samsung tvs going forward. Sony OLEDs are looking real attractive right now. This is rediuclous that they cut support so early into a products life. Samsung 'smart' tvs are 'dumb' tvs.
I have 10 repeat 10 Samsung TVs in my house wit h2015 built dates and I will NEVER buy another one and throw these out if Samsung doesnt do the right thing tof their customers and change the permissioning for Disney+
Pretty esy decision.
