before starting a running activity I am shown connected sensors, since I installed ver. 15.19 "timelapse" is also shown what is it about?
I get exactly the same since I bought a new strap for my hr sensor (Polar H10). Now I have a medium sized strap (M), before I had a small sized strap (S) and I didn't get this "timelapse", even after 15.19 update... I don't know what it means or the difference but I see that my hr sensor with the new strap is working without any problems...
