Im new so plz bare with me on this. I have (2) roku expresses in my home. I was casting on both using web video browser. Now I can not cast on either of them. I ck the ip on screen for roku and says 10.10.0.88 so now I'm suppose to see if my phone is on same? When I hit set up manually on my account page (10.10.0.88) it tells me no streaming device found at this IP address. I've restarted roku,phone,Im not using a "phone service " but did pay the $30 cost to connect to wifi service. I can "add channels and view " all that stuff I just can't connect to be able to cast videos,pictures and such. Thank you community. I have Samsung J3 - 7.0/ROKU Express
