Prefer trailer-friendly is not working anymore

As I drive with a caravan the Prefer trailer-friendly feature is very essential for me. But since the last update it is not working anymore. I enabled Settings → Chargers & Networks → Prefer trailer-friendly but when I plan a multi charging route then most of the selected charging places are without the trailer icon. I tried to disable and enable the setting with no change. Issue in Android App and as well in web portal. See
