Cannot cast Netflix from Iphone on Roku express

I can mirror my iphone with roku express perfectly and can cast everything such as youtube, other apps to my big TV screen (Phillips) via airplay with Roku express except only Netflix. When i access to Netflix on my iphone i can also see it on TV (the page where u can choose the movie you want) but when i press to play any specific movie on my iphone to cast it to my big tv screen, my iphone always shows the message as attached screenshot while my TV to which the roku expess connected to dont show anything. However if i just watch that movie on my iphone without mirroring/casting to Tv via rokun airplay then everything is normal and i can watch that movie all over my iphone screen. Anyone encountered the same problem pls advise me? Many thanks!
