Thanks for reply’s - So In answer:

Q1 - I drove for 20mins in pure today and there was definitely no heat with the aux heater off.

Q2 - later with the aux heater off in the centre menu, I started climate from the app, which fired up the aux heater and then warmed the car despite it being disabled in the car menu.
Will test tomorrow to see if when plugged in it still uses the aux heater to pre heat the car or not.
