How to edit an exercise?

[agsurf5]

I forgot to stop my exercise after I finished. It was a bike ride.

Is there a way to edit the exercise and reduce the time of it? All the stats for it are wrong.

I believe you can see the details or delete the exercise, but you can't edit it.

Hi @SunsetRunner & @agsurf5,

If you have the Windows 10 app, it will let you edit the start and stop times. Just go into the activity, and click the pencil icon in the upper corner. Then it will let you change the start/stop times.

Mac, ipad and an android phone...

I have windows ten and don't find the pencil. Since my exercise shows splits, I should be able to erase one split. Why doesn't fitbit notice I forgot to turn off the exercise tracker. It does it on an apple watch.
