I have multiple Roku devices. On my Roku tv I can cast or screen mirror my smartphone to the device. When I try to cast or screen mirror Facebook on my other device, my smartphone doesn’t even show that device as an option, but if I try casting or screen mirroring YouTube it shows up. Any help would be greatly appreciated.
Thank you.
Need more information.
Need device names+model #s, phone names+model#s, connection type/info.
Casting is "remote control" whereas mirroring is "remote display".
Roku supports DIAL (casting), Miracast (mirroring) and AirPlay2 (casting & mirroring - 4K devices only).
GoogleCast (ChromeCast) is not supported.
Android and Windows devices support Miracast/GoogleCast, whereas Apple devices support AirPlay2.
Without knowing more, you can try:
1) disabling/enabling WiFi on your phones/devices, or
2) rebooting all the devices (Rokus/phones/tablets/modem/router/gateway) or
3) switching WiFi connection from 2.4Ghz to 5Ghz or vice versa on phones/devices or Rokus
4) resetting the network connections on all devices
