The software update was completed and the range has increased as expected, the day before at 100% I had a range of 165 in eco mode, and I now get 200.
The fan doesn't change the range at different speeds once it's on and I don't see any difference based on the climate control temperature, so I think the heat pump must always be running and divert heat as required.
Need to see how the charging curve has changed when I get an opportunity to use a public charger.
