This may not be a bug and might be expected behavior, or something I did on my end. I'm just curious if anyone has seen this before or if someone else can test it out.
I was doing some treadmill running last night and had my 235 on Indoor Running mode. Everything was fine until I had to take a phone call and paused the run. When I returned a few minutes later and resumed the run, the watch decided I was no longer running indoors and it used the GPS. I've attached a picture of my pace chart.
Any ideas? User error or bug?
