Seat heating after restart

Hello all, maybe this is a normal behavior with DS, but I have not experienced any other car like this: if I turn on the seat heating in our DS 3 year 03/2022 and put the car off, lock it and so on, then the last adjustment of the seat heating remains, i.e. the next morning it is on again. Is this so normal and wanted? I always know this only so (Mercedes, VW, Fiat, BMW, Mini, …) that after ignition key pull off (at least after a g I don’t think it’s very disturbing now, but maybe there’s a problem after all. Because since we have the car, for example, the start-stop automatic has not even worked (it always only flashes friendly green, despite battery charging). Maybe there’s some connection or so… Thanks and greetings.
