GPS runs discrepancy between my phone and laptop-Charge 3

[KWHa]

I have used my Charge 3 successfully to track my runs for months.  Recently, however, the GPS data (map, elevation, and pace by time and distance) from my runs is not appearing on the dashboard on my laptop.  Specifically, while my phone accurately shows my route on the map and calculates pace/mile and distance, what appears on my dashboard is totally different (i.e. a route that does not match my actual route; completely inaccurate elevation over distance).  As a result, I cannot look at of the details of my run (which is only possible on the laptop-based dashboard.  

This problem started at the beginning of November, and I have not gotten an accurate reading since.  Interestingly, when I track walks, I get better data.  Although once in a while I lose GPS, my phone and my laptop tell the same story whereas when I run, I get different readings.

1. Tap the Today tab, and tap your profile picture.
2. Tap Set Up a Device.
3. Choose your device and follow the on-screen instructions to continue.

Wait. Do you mean delete my current device and re-install it?

By the way, I only have this problem when I track a run. When I track a walk, the GPS transfers to the laptop-based dashboard just fine.

It is not necessary deleting your current device but just re-install it.
