I have tried so very many times to get Roku to play back. Tried to link using code from Roku settings. The code is never accepted. It calls for code on screen well code is not on screen!! Whenever I try to sign in to my Roku account it takes me through a dozen or more robo checks are you human pics to detect always running out of time after going through st least 12!! It is freaking maddening and the only app I have any trouble with.
