Hello! Today I completed a walk in several different subdivisions (I drove to each one), and had Strava paused. I didn’t realize it would transfer a straight line in between the subdivisions I walked. Is there any way to erase the line between the two subdivisions where I drove, but still show the streets in the subdivisions highlighted and complete?
You’ll need to fix the activity in Strava.
That’ll probably involve somehow splitting it into multiple activities. 
I can’t offer any assistance with how you’d accomplish that. It’s possible that a community member can share details on how to this…
I was able to find your Lunch Walk | Strava … it looks like there might be just the single pause/drive situation, in the upper right … if that’s the case, you might get lucky & just be able to edit that triangular extension out of the activity? Again, I don’t know how to actually do this, but maybe this info can help someone else explain.
