Hi @Hc311,
Greeting from Roku Community.
Let us help you get connected with AirPlay on your Roku TV. Before you can use AirPlay with your Roku device, we need to check the basic requirement.
- Does your Roku TV run Roku OS 10.0? (To find this information, go to the home screen and select Settings > System > About.)
- Is your Apple device compatible? iPhone, iPad, or iPod touch with iOS 12.3 or later and Mac with macOS Mojave 10.14.5 or later
- Is your Apple device and Roku device on the same wireless network? (Confirm that your Roku device and your phone or tablet are connected to the same band and network name.)
Once everything is confirmed, could you try re-connect your Apple device to your Roku TV using AirPlay? We also suggest you restart your Roku TV first before the process, to do this go to Settings > System > Power > System restart.
You can see more here: How to use AirPlay and HomeKit with your Roku streaming device
Keep us posted on how it goes.
Regards,
Nimfa
