Within ABRP running in Apple CarPlay the current traffic is not shown (I'm Premium user). Live Data options (Live traffic etc) are activated. Observed this over some days now. I would expect to see traffic jams (like I'm in one on the picture) are visualized among the route.
On the alternative route it seems there are some shades of grey, I'm not sure if this refers to traffic conditions.
