iPhone 11 Pro Cannot access AppleTV using Remote App

[davehutch]

Hi all, strange one. I have an iPhone 15 and if I ask Siri on the iPhone to play BBC1 on the AppleTV, it is quite happy and does it.
If my wife does it on here 11 Pro, the message pops up to says it can't find an Apple TV on your Home and we need one to our Home.
Is this referring to the HomeKit? The odd thing is that I deleted the HomeKit app and never added it to my Home anyway.
We both have the TV Launcher app installed on our phones.

Is she signed into the Apple TV? That may be the problem.

It's using my account by default but she is listed as another user. I re-downloaded HomeKit and straight away it asked me if I wanted to connect to AppleTV. It doesn't ask her that so maybe I need to switch accounts and add the AppleTV on her HomeKit as well?
