That version number seems strange. Mind if I get some more info? What year / model tv are you using?
It is showing v2.0.8 as a 2016/11/10 release in the Samsung App Store, but their store also shows it near the top of "What's New" today. (I'm sure Samsung have been 'fun' to deal with.)
My email is in my HN profile, happy to help if I can!
