Mine is slow to heat up and max heat is sub par max heat. I just leave it on floor/defrost level 2 in the cold. Dash/floor results in a whistle on level 2, which is unfortunate, as the rear get no flow without the dash, which is idiotic,. That should be floor and dash with flow controlled by the rear seat passengers. My "Queen of noticing anything not right and mentioning it immediately" was quick to note this when she had to use the rear seat.

Neither of us was best pleased with heating system when I first got it but perseverance does fix it.
Mine heats up within 5mins and that was after a couple of days at -6c

I do see that, and and that's on the service list. The unit sending NO air to the rear unless it's on dash though, seems to be the ducting scheme.

Unless of course, mine is malfunctioning. If changing function on 3 or higher, I can get a flap noise that sounds much like 25yo Zimm playing "double D motorboat" in Reno.

I have had that at one point, even after the bleeding when on full heat auto, I have a video of it but it's to large to add to the site and I'm an idiot when it comes to computer stuff
Mine has seemed to have sorted itself by using it now it's working

I have been very fortunate with my HVAC system, no issues. Only had the vehicle for 2 months or so with 1200 miles on it (3/24 Build Date Build # 17256). Until recently I was using manual control and found the system temperatures would swing high and low needing constant adjustment. I was not happy with this until I tried the Auto function. Once I changed over to Auto I have not touched the controls since. Maintains an even temperature and warms up rather quickly.

What steps did you do? What was the delta!?
I made sure that the coolant was topped off, then followed the procedure a couple pages back on this thread. I didn't IR the vents or anything, but over 60 miles and stopping/starting the engine a few times, I couldn't detect any fluctuation in temps in the cabin for the first time. It used to be every time I made a stop somewhere and got back in, I'd have to adjust it, and often on the road it would go along fine for a long time, then suddenly go psycho on me and go up or down 20 degrees or so. Anyway, quite simple to follow the steps. Good luck-hope you have some success as well.
