Went out for a ride earlier this week and was out to set a new PB for a segment on my Strava. Got home after the ride and found the only thing recorded was a straight line. Checked the settings and went out for a ride today and again, nothing but a straight line. Ended up deleting the app and reloading it. Went out for a short ride and it seems that has corrected the problem. Will find out tomorrow when I go for a another ride. My phone crashed last week and ended up resetting itself and I had not given the app a second thought. I guess I should have.
Frank.
