I have a TCL 55R615 Roku TV. I was able to connect to the TV from my iPhone 6S. Recently upgraded to an iPhone XS Max.
I login to the Roku app and when I click on “connect” I get an error that states “device is not available when you do not have WiFi”. The IPhone and TCL Roku TV are on the same network & subnet.
Can anyone tell me what I need to do to connect the Roku app to the TCL TV?
