Hi not sure if this may help I’m now over 10,000 miles in my MG5 and it’s my first winter in an EV so still learning, I tend to drive most of the time in Eco mode, and in this mode if you use Auto for the heating set around 23/24 degrees you will see on the heater control panel the Eco light will be on while in this mode, not sure what this does but I think it cuts down the heat output a little and maybe the fan speed as well, so turn the Eco button off ( no light ) and see if that improves matters for you when in the auto mode the lights on the heater panel that will be on are - Auto, A/c and Eco so when driving in Eco mode I turn the Eco button off.
In the other modes normal and sport this light on the Eco switch never comes on
Anyhow you can only try it and maybe feel the difference perhaps I do and my passenger I said it improves when I turn of the Eco button so give it ago and maybe feedback what you find in you car.
One way you can see this taking effect is to switch on the demist function and then back to auto while your driving in Eco mode
