Resurrecting an old thread in the hope that developers are still watching...

Over the last two months Traffic in the Drive app has been slow/intermittent to load, requiring many app re-starts, but now has completely stopped loading. I have originally installed it using N9QT (option G-2) and it has worked flawlessly for several years.

I still see the "Loading Traffic" banner at the bottom of the screen upon Drive startup but after 5-20sec it disappears and no traffic is shown.
Any advice on how to debug this? Is there a possible timeout that can be extended to acquire the information needed to display traffic?
