I agree as the Roku is the most popular streaming device it should have had a app day one. Tells you how Amazon is crushing it with there Fire TV which is based on Android yet Android TV gets the fewest apps many they never get that are on the FTV.
Not sure if it's been mentioned previously, but for the SF bay area RSN, CSNBA, Warriors games are blacked out with this service. I don't know about anyone else but seeing the games is basically the only reason to have this channel. I expect that Giants baseball games are also blacked out. If there was a disclaimer noting that pro sports games(maybe even college?) are blacked out with DirecTV Now I missed it.
