Location Tracking Tracks collecting outside Geofenced area

[elpinguino]

I've set up a geofence in Field Maps so location tracking takes place only within the project area (red boundary). As you can see here there are tracks points getting collected outside the boundary. Do you know why that is?

Some context this area is at the foot of a huge mountain so potentially it could be a gps issue? It is happening throughout the day, not just at a specific time. It is happening to all team members, not one person or particular device.

Altitude - 300ish

Battery State - Unplugged

Horizontal Accuracy - 3900 mostly

Signal Strength - not populated

Vertical Accuracy - Mostly single digits

I'm adding this article as a reference point.

@elpinguinoI would recommend double checking your geofence setup. If you had a couple of points just outside the perimeter, I could maybe chalk it up to gps issues, but based on your screen shot, I don’t believe that’s the case (can’t know for sure without the geofence setup info, at the very least). But that’s where I would start.

Thanks for responding @KerriRasmussen . Since posting I think it may be a case of we have some users on older versions of the map, so the most recent geofence parameters haven't been applied.
