TV models released every year have different Tizen versions.
If I make a tv app on Tizen 6.0 SDK, is it working on Samsung Smart TV(2016~)?
Hi Fison67
See this trhead it may help
And on this page it calls for TV Extensions 2.0 or HIGHER so I would guess that the Tizen 6.0 SDK is fine.
Hope this leads you in the right direction
