Different behavior with AppleTV vs iPhone, Zwift + Activity apps

For some reason if I use Zwift on my iPhone, the workout gets pushed into the Activity app on my iPhone. But if I use Zwift on my AppleTV, it does not. Yes all iOS and software versions are up to date/latest.

This is with a Wahoo KickrBike, Wahoo TickerX, AppleTV 4K. I do have an Apple Watch S4 as well though that seems to be very hit or miss so I’ve not bothered playing with it.

In the Health app on my phone, Zwift has all/full permissions set to On. However in the Companion app there are NO permission toggles, only Data (and it shows no data…)
