This has probably happened to a few of us. By pressing the start button at the beginning of a cycle I must have accidentally double clicked it, so that the entire ride took place in the "paused" status.
I didn't notice as all my key metrics were active: heart rate, cadence, speed, power etc, but just hadn't spotted that the distance was stuck on zero.
Ideally I'd prefer the Play and Paused icons to be permanently visible but I can't figure out if it's possible
Any suggestions?
