In my last 2 running activities my Fenix 5X stopped recording GPS data for about 2km, but all other data was recorded correctly (pace, distance, speed etc.). In fact the final distance and the average pace are correct.
By analyzing the fit file at https://www.fitfileviewer.com/ and looking at the recorded data, I can see that all data is recorded correctly and only the latitude and longitude data is missing for about 2km.
It had only happened once in the past, about 1 month ago. But now it seems like a recurring problem as it happened both yesterday and today.
The Fenix is practically new because it was replaced under warranty with a new one at the beginning of September.
