Why does the app say "I have no/bad GPS"? Or why does it sometimes take longer to restore GPS quality?

There are several factors that may affect your GPS quality. For instance, riding into woods, in urban canyoning or in cloudy weather may disturb the GPS signal communication between your smartphone and the satellites.

Once your GPS tracking provides inaccurate location (or other) data while tracking your activities, this state is named as bad GPS. This may result in having inaccurate or missing activity tracking data.

If your device loses its connection to GPS satellites, this state is called no GPS. In this case, no location data will be recorded.
