Not Getting Heart Rate from Apple Watch to Zwift

So getting your heart rate from an Apple Watch to Zwift is theoretically possible, but personally it is a bit hit and miss In this video , it refuses to work. But when I try my lovely Garmin watch it gets the Bluetooth signal instantly. Very much the Garmin make Apple look clumsy and amateurish, which is exactly because it currently in in all things related to a serious athelete. One could argue of course that was not its design point, but I could counter that surely the Apple Watch Ultra could have been a little more competent [than the Apple watch S8] Anyways see this video for an example of it working    • Connecting Apple Watch to Zwift   Actual sequence IMHO should be Start Indoor Bicycle trainer, in my case TACX Start Zwift App (in my case on an Apple laptop) Start Zwift Companion on phone. Obviously bluetooth is switched on Start Zwift app on Apple Watch The Phone app should link to Watch and Pair On Zwift app on laptop goto Heart Rate and Search Apple Heart rate should appear (Or in my case nothing, but Garmin always works, every time)
