Yes, I believe it is now worse than it was before (just after the reading of speed signs was implemented). Main problem seems to be that it reads a speed sign, shows the correct speed limit, but then you go through an intersection and the speed limit changes, only when the car doesn't see the new speed sign (e.g. car blocking the camera view of it) it does not update the displayed speed limit. It should stop overriding the map based speed limit in that case (when the map-based speed limit changes it should stop following the camera-read speed limit).
I'm sad to say this worked way better on my 2018 (and even 2015) BMW.
