During the initial setup of my box I was prompted to setup my phone over Wifi/Bluetooth and I began the process but there was a hiccup along the way which forced me to leave this step incomplete. Now that my box is setup and running perfectly otherwise, when I attempt to setup my device (Samsung Galaxy S8), using the Google app it doesn't recognize the box on my phone. (I do have WiFi and Bluetooth turned on.)
Sidebar: I'm entirely new to Android TV and a fairly novice user of apps that require pairing and the like. It seems like it should be a simple fix but I simply couldn't work it out.
