AeroPod, PowerPod and Newton

I went on another ride today and i'm getting the same problem. hmmm

hi,
i am trying to merge gps & heart rate data into my powerpod's file. i get some weird results when isaac tries to sync them. i uploaded the gps data to strava, no worries, but in isaac it shrinks the length. can i sync it manually?

any help is appreciated, thanks.
