Long press still gives you info, just not as much!
If you are being guided (route planned), then I would expect it to let you know about traffic. I'd want it to let me know there was a camera ahead if I was just tootling about. 
I'll try the long press next time I'm out.
No I wasn't being guided.
I hadn't touched the NAV at all. Just got in the car for my normal drive to work and after 5 mins of driving it came over the music that was playing that there was congestion ahead. I actually thought I had imagined it but it repeated it again.
Right enough when I put the map on I could see the line of cars appear on the screen.
