I saw it for 3 times.
1st time I stop for 20 min. Result: track is shorter than ride for 10km.
2nd I come under the bridge for a 10 sec. After 5 min I try "contunue later" option. Result : straight line between bridge and my position.
3rd time : I have to start new activity. result: 2 tracks instead one.
Gps is ok, I turn on special field.
Not every ride. This problem appears after updating to 23.10. Earlier all was OK.
