EQE stupid route with activated charging planning

Hello, did any of you activate the automatic charging planning? I disabled it, otherwise there are no alternative routes available and I don’t necessarily need it on my usual routes. Now I had to go from Stuttgart to Munich and back this week and wanted to know which SoC I will arrive with in M. So I started in S and then after a few km on the motorway (height airport Stuttgart) with active navigation the switch for r Charging planning enabled. Then like the route recalculated again and suddenly the planned arrival time was just 20 minutes later than before the activation of Electric Intellgence / automatic charging planning. At first I thought it was a traffic jam on the way. But when I looked at the route in the zoom, it turned out that the Navi at Gruibingen/Mühlhausen wanted to pilot me off the highway and over country roads high up the mountain ascent. This is how it works when there is traffic jam on the motorway. But there has to be a long traffic jam to make sense of it. And on that day there was no traffic jam. After I then deactivated Electric Intelligence again, the Navi decided again for the right route I drove without traffic jam completely on the highway to M. So this system is not usable. I wonder if the Mercedes engineers never test this? If I read what progress VW makes with their SW, then I’m very jealous. Mercedes seems to be at a standstill. PS: who doesn’t know so well in the south: there are no two possibilities between Stuttgart Airport and Munich. There is the A8, which leads directly from S to M and the section that wanted to drive Electric Intelligence off the motorway runs almost always parallel to the motorway.
