Congratulations on your new MG 4 X power,
What a fantastic machine it must be with all that power.
Totally agree about the one pedal driving, it makes driving around town so much easier.
I know what you mean about the changing overnight cheap tariffs with some chargers & providers, They seem to keep moving the goalposts on that one. I would have a search on the MGEVs MG 4 forums to see what electricity suppliers others are going for.
I shall be looking into other tariffs for mine shortly.
Yeah the car going back to the default setting every time you switch off is a pain for sure.
I read there are software updates for MG's to make the charging handshake between car & the Tesla supercharger network more reliable.

It seems Ad Hoc what software updates the dealerships do, For instance my ZS EV hasn't had any software updates whatsoever in over three years I've had it
I'm not particularly bothered as the car has been faultless.
