I recently bought a tcl roku tv and I have been trying to use smart view to screen mirror but smart view keeps telling me to unplug the device I'm trying to connect to (the tv) and plug it back in. I've done this a hundred times and it still won't connect. I can use the apps that you can cast downloaded media to the phone but I want to actually mirror the screen. Can anybody help?? Thanks!
Update: I ended up just returning the TV and buying a samsung smart TV because it's super easy to mirror from my samsung phone to the TV. Now I can mirror from my phone AND I use next to no wifi to do it. I can still get roku on it if I really want but we didn't use the roku app itself much we used other apps like Netflix and disney plus.
