ABRP Reference Consumption incorrect?

I am on a 1,000 mile trip pulling a U-Haul trailer with my '23 Lariat. I have previously successfully used Tesla superchargers on a couple 1000+ mile trips. On this current trip, when I stopped at the first 2 Tesla superchargers, I had something odd happen. I am using the Tesla membership, so I can get the discount. I plugged the truck in and started the charge with the Tesla app. It charged for a couple minutes and then stopped. I restarted it, and it did the same thing. Restarted 1 more time and it successfully charged.

Drove further, tried charging at Tesla supercharger, similar thing except this time the Tesla app gave some kind of warning like "unable to charge at supercharger right now". I then tried Plug and Charge instead of the Tesla app and that worked fine. I avoided Tesla supercharges for the next five charge stops and only used Ionna chargers, which all worked flawlessly.

Anyone have any thoughts?
