I'm trying to mirror my galaxy note 9 screen on my roku express. I have screen mirroring turned on in my roku settings and both devices are on the same wifi. When I try to connect my phone it prompts me with accept button. When I click accept it shoes done kind of pear logo and a pop-up at the bottom says video loading even though I'm on my phones home screen. When the loading bar completes it automatically shows my roku home screen and not my phone's home screen.
