Failed adoption of consumption

I need ABRP one or two times a year when going long distances. One of these journeys happened last week, with a trailer (as every year). So I did this trip - with a trailer - and - with ABRP - already last year and i cant remember such a mess.
The charging stops got planned every 40 minutes, soon after starting the trip the arrival charge went up and up and up. So when I was at the planned stop I still had 40-50% charge. ABRP NEVER adopted the correct usage, even when the arrival charge was at 40% it didnt re-plan. It was about 800km in 5 days so plenty of time to adept. :-(
