We just moved our roku tv to a new home but didn't change the wifi. My tv has my old wifi on it and no remote. We've been using the app as a remote but it's now connected to the new wifi so the app won't work on my tv. We have no Hotspot on a different phone to use. Idk what to do
You either have to configure the new Wi-Fi to match what the TV was last connected to (same SSID/network name and password) or get a remote. A lot of universal remotes support Roku TVs.
