Trace on map partially incorrect - taking 'shortcuts'

Every once in while the map trace is skipping parts of my run. While distance and lap points are typically correct, the trace just draws a straight line in between. I frequenty run those routes and normally the trace is correct.

Here are (2) recent examples that happened within the last 2 weeks. These are screenshots from GarminConnect web version, but are consistent with what's shown in on the iOS app, Strava, but also on the watch itself. Therefore, believe it is a watch issue.

Case 1

Case 2: overall view

Case 2 - overall view

Case 2: zoom in: blue line is what trace should have been

Case 2 zoom in - blue is what trace should have been

Case 2: Strava view

Case 2 -Strava view

As an aside, I have had this issue on and off with this watch (and maybe even other Fenix models I owned before). This has also happened with earlier f/w versions - beta and released.

These (2) cases happened with F/W 10.0.

How can this be fixed?

Do you have auto pause on?

Yes.

Pls elaborate as to why you have asked?

Straight lines can only happen when you stop the activity and restart it at another point. This can happen with auto pause if you are too slow. I had the effect that the closure of my bike gloves could stop my Fenix3, but this never happened with the smaller F5+.

Bad GPS-reception looks different and I never saw a complete loss of reception over a longer period with any of my Garmin watches in 10years, not even in Greek gorges.

Hi Alan; Understood and I think that's a valid point. However, I don't think this is the problem here. If you look at Case 1 you see the lap markers (1/2 laps), which plot the my route correctly. Also the overall distance is correct. (I also got full readings (pace, etc. during the missing stretches)

I suspect something else. It seems that the watch is working fine (receiving GPS signal, tracking distance) but is simply not plotting the route.

Yes, I have.

Update: I called Garmin Tech Support today. They suspected some 'stale GPS data' on my watch and had me delete the RemoteSW and the NewFiles folder on the watch, followed by a power cycle (hold upper left button for >15 sec) to rebuild the deleted folders.

It's a bit early to tell, but my run this evening went OK.

I am carefully optimistic at this time.

Did it work that time? Or how did you solve it? My Fenix 5x just started doing this last weekend.
