Please try these options to resolve the issue:
- check the GPS settings on your device: Settings – turn Location Services on and enable ‘While Using’ option for this app;
- go to the app Home screen, tap Start – Begin – Settings icon in the upper left corner – turn GPS on and select “Outdoor” mode;
- you may need to wait for a couple of minutes to get the signal since GPS depends on the weather;
- before starting your run make sure that the signal is ok and at least one GPS indicator is shown on the screen.
