I saw reports elsewhere that some started having the charging issue about 10 days ago with an earlier release. One person seems to have discovered that if he plugs in to his HPWC with the car set to anything above 70A everything works as expected - it ramps up to the setting and then he can change it to anything he wants and it charges as expected.
If he plugs in with the car set to say 50A then he also gets the "half rate" charging error no matter what setting he chooses. I'm dip switch limited to 64A due to being on an 80A circuit so I can't easily test this theory.
I would do this, and will later if it still needs to be done, but my wife has the car at work now. When I tested things last night I did not realize that there was a known issue with a threshold above and below 70 amps, and I had my charge rate set above that, so didn't actually manage to test what we're now interested in testing.
I just tested this, and for some reason my dual charger P85D updated to 2.12.126 this past Friday is not afflicted with this bug.
My wife had plugged the car in when she returned home from work and scheduled a charge to start at 72 amps at 3:15 AM.
--I went out to the car, unplugged it, got into the car, changed the charging rate to 64 amps and turned off scheduled charging, and then plugged the car back in.
--Charging started immediately, of course, ramped up to 32 amps quickly (actually I noticed a momentary blip at 33 before it settled at 32), paused at 32 for perhaps 45 seconds to a minute, and them ramped up to 63. It never did get to 64, and I'm not sure why. Perhaps I have a minor bug in that respect.
I then set the scheduled charging, changed the rate to 72 amps, unscheduled the charging, because I wanted to make sure the car would charge at 72 amps, and not 36, and watched it pause at 36, and then ramp up to 71. At that point I just reset the scheduled charging, and fully expect that the car will be charged to 90% shortly before my wife intends to leave in the morning.
If I didn't follow the correct protocol to reproduce the error, Mike, let me know, but I'm pretty sure that I did.
