I would like to ask the same question, I have the same TV, I can get apple and Disney but not discovery plus app, given the price of these TV's I would of expected the same download capability as my phone or is this a discovery problem?
I have just subscribed to Discovery plus only to find that the app is not pre- installed on my tv and Samsung will not support the app from Google play store. Any ideas or updates would be appreciated. Thank you
Discovery app now available, I contacted discovery last night and they said they were adding the app to samsung TVs over next few days, I've just checked and it's there and I'm now watching it! Result guys!
