Can’t log in to Apple TV on my new television

Another user (mygreensocks) suggested this procedure from Roku Support staff, which reportedly helped several users.

1. Remove the Apple TV app,

2. Shut off and unplug the TV (or streaming device),

3. Wait 30 seconds,

4. Plug the TV (or streaming device) back in,

5. Reload the Apple TV app.

Else try the Network Connection Reset, as suggested by user Jarieta.

Generally speaking, if you can install the app from the Roku store, it *should* be compatible. Does it say anything other than that error message when you try to login?

No more updates on this? I ha e a new Hisense Roku TV and can't log on to Apple TV. Every other streaming service works

Thanks! This worked. I ran software updates on the Roku TV itself expecting to actually update the channels. But removing the channel and readding did the trick.
