By the way, here is a work around to watch Apple TV on your big TV using your laptop.
I have Windows 10 on a fairly new laptop - not sure if earlier versions of Windows can do this, but I think it has been available since Windows 7 - maybe Vista. Pretty sure the Apple OS can do this too.
First, sign into your Apple account on your laptop, and navigate to watch Apple TV.
On your TV, select your Roku as the input - just leave it on the home screen.
On your laptop (remember, this is for Windows 10 - your OS may have a different path to this feature), go to Settings > System > Display > scroll down to Multiple Displays, and select "Connect to a wireless display". In the pane that opens on the right, you will see available devices you can connect to. If you don't see your Roku device, click on search. This works via Wi-Fi, NOT Bluetooth, so you don't need to turn that on. When you click on the Roku device, you should see your computer connect to your TV, and play whatever is playing on your laptop. And this works for anything you might watch on your computer - your own video library, YouTube, whatever!
