Can't see multiplayer

Hi,

We are experiencing exactly the same problem: when activating “All players” or “Live players” we never see any player on the world map.
Also tried New York / Heathrow like JointedOrc6852 stated.
Exactly the same behavior with the “Teredo” : first it says “komt niet in aanmerking (Dutch)” i.e. something like “is not eligible” in English, but after fixing everything OK.
However still no other players visible when opening the world map…

Fortunately, all other online functionality (live traffic, weather, airport info, etc.) works normally, so it is certainly not in the online connectivity …

Has anybody experience in executing the steps as mentioned in:

I am absolutely not a “network expert” and do not dare to perform the last step “DISABLE IPV6 IN WINDOWS 10” .
Can someone indicate whether this will not affect other programs, internet connectivity, etc. on my laptop ???
