Happened to me 4 times in last week.
At some point map just stuck – displayed location becomes incorrect. But my path continues to render, same to rider arrow direction.
Here at the photo you can see my path made out of screen bounds, but displayed location is still a some point in the past. And it will never return to displaying actual location no matter how long you will wait
GPS profile: Auto-select
Firmware version: 25.25
Temporary solution is to turn GPS to OFF, then re-enable it.
