Issue with tracking GPS workouts

[Marlin1894]

I’m have a Charge2 And use an iPhone 6s with iOS 13.4.1 and Fitbit app version 3.21.

I’ve had no real issue until the past few days but just occasionally I would start my walk and without even moving my Pace would start jumping up and recording movement when I hadn’t gone anywhere.  Stopping the recording, deleting the activity and restarting the walk would solve the problem.  For the past few days I can’t get normal logging and could walk a kilometre in 4 minutes if I let it run.  I have disconnected then reconnected the GPS, deleted and reinstalled the app but haven’t been able to solve the problem.  However, Strava runs fine and has no problems with the GPS.  Any help would be appreciated.
