The nowtv App inbuilt into your Samsung Smart TV should work fully and integrate with your Samsung TV remote controller when using the App.
What sorts of functions are not working with the Samsung remote and has these lack of controls on the remote always been the case since you purchased the TV and used the App ?
I don't own a Samsung Smart TV myself, where i would assume the only advantages of the nowtv smart stick would be pause live TV and voice content search (where you won't be able to use the smart stick remote controller with the Samsung Smart TV inbuilt NowTV App).
Perhaps if you post the model number of your TV and NowTV App version, then maybe somebody who owns the same model line TV will offer you some further help & guidance.
