I don't know what your charging set up is at your home. I have a Tesla home charger on a 60 Amp breaker with a 48 Amp output and I have always charged at 48 Amps when at home.
The Tesla wall charger is higher. The NEMA 14-50 was reduced to 30amp a couple years ago.
NEMA 14-50 is a plug type. It indicates a 50Amp rating. Current Model S onboard charger is standard 48A. HIgher end models or those with upgrades, can have a variety of configurations. Older cars had 40A/80A dual charger option. Some cars have 48A/72A high amp charger option (100D and P100D now come standard with 72A high amp charger).
The power supplied to the EVSE determines the charge rate. Some EVSEs can only handle 30A (on 40A circuits). Technically the max on a 40A circuit is 32A (which is what the Bolt maxes out at).
Now, the version 2 mobile connector does max out at 32A now but version 1 of the UMC was capable of 48A (which requires a 60A circuit). I charge my car at 32A even though I could do 40A because I rarely need anything faster for overnight charging but the car is capable and my circuit is capable of delivering up to 40A to my car safely (on a 50Amp circuit, with a NEMA 14-50 outlet).

Sounds like you need to come here to Central or South Florida. Bad traffic, lot's of construction and heat... lots of heat!
Yeah, I had the one that was 30-32amp. Looked at my phone today and it was going at 40a

Installed update. The ping ponging is gone and the vehicle blind spot avatars are more stable.

I'm curious, any of you who got upgraded to 40 lodge any complaints about 39 via executive escalation? I'm not super concerned at this point as it sounds like 40 does even less than 39 and doesn't really fix much of anything, just wondering if there was any "selective upgrading" to 40.

What is the size of your USB stick? I had a 64GB one at my wife's Model X and had to reformat or fix almost every other drive. I got the update on my Model 3, installed a 16GB there and no problems at all. Did the same for my wife's and it is working like a charm for a week now.

Interesting. I ordered a 32gb stick but it hasn’t arrived so I’ve been using just an old 4gb usb I had laying around. Worked for a day or so and then stopped. I have fixed it a couple times this week. But it’s stopped again.
BTW. I don’t start and stop it when entering and exiting the car like others have suggested as a workaround fix.
I have the latest Tesla android app 3.6.0 and also version 39.6, yet I don't see on the android app any of the new functionality of media or the ability to initiate a software update from the app. Does anyone else have the android app and is it showing the new functionality?
But does it still play my favourite song: "Loading Error by Tesla"?
U need to be in car to see media controls ..software button won’t show up unless u had previous version of 39.x loaded already
This is incorrect. The Gen 1 UMC draws a maximum of 40A, plugged into a 14-50 outlet (50A circuit).
