Which I totally do! But it’s downstairs and when I’m headed upstairs where the Roku is, I find myself wanting to mirror. So is only iOS to Apple TV? Or if it’s on You Tube? I think it will mirror to my downstairs Smart TV or maybe that was one of the kids.
You can only mirror your iOS device to an TV.
However. If you have a roku or a smart tv with YouTube installed, and are on the same WiFi, you will be able to open the video on those devices.
Ok I thought I might have done that before downstairs! So I can mirror YT but I got nothing with any other vid. Maybe I’ll have to grab our Android tablet from the kitchen when I want to.
