The London Pretzel trouble

Today I tried to accomplish the London Pretzel mission which is 55,7 Km long in the lobby, but after I drove for 85 Km I still haven’t reached and didn’t accomplish the mission.

Did you do any manual turns?

No, I didn’t. I left the app 2 times to answer messages though. But I thought maybe, I just haven’t reached the finish, because some courses are actually a lot longer than they’re in the lobby, although mostly shorter ones. As noone has pointed that out yet, I assume that this isn’t the case for the London Pretzel. Am I right?

It has a 0.5 km lead-in. See
