Any tips out there for getting the traffic working consistently? I get info at the start of the journey (sometimes), but never when underway. I have checked privacy settings (all as open as poss, sharing everything) and both the car and the online portal show an active subscription.

 

Today I deliberately asked it to set a route that could have used a trunk road that's closed all weekend and it offered that route to me as an option that was clear, with nothing untoward shown on the map either. I was only 5 miles away from the closed road, so would reasonably expect it to be downloaded live data.

Good luck with that, mine is random at best, but I don't use the SatNav for routing as its so poor. I personally use TomTom for the traffic and speed cameras, nice and easy through Apple Carplay, but so is Waze/Google..... 

The car occasionally get the traffic information right and updates whether or not you are using it to navigate, but I would never rely on it.
