Hi,
Thought i would share this finding . Had issue a few times where Zwift didnt manage to change the Wattage when it was changed as part of a workout , and this is key, where the wattage was the same for > 15 mins (this is quite rare if you think about it)
Fix was to turn off sleep on the Apple TV as per below . Did (2 mins @ 125 watts / 20 mins at 150) x 2 afterwards and appears to have fixed.
