Bugs of notification geofence
By the way here is the KML & GPX file I created using Kml2Gpx for circle geofence for your analysis. What could be the issue that Traccar Server Geofence Enter and Exit detects within 4 seconds of entry into custom uploaded geofence.

It's exactly the issue I told you about before.
I don't really get you. You mean polylines or polygons? Circles not supported?
Uploaded GPX files custom generated KML2GPX seems not be able to determined by Traccar server if a tag device enter or exit a custom created geofence.
What parameters in the GPX file is causing the issues. Can you please show me what format of GPX file is supported by Traccar server?
I don't know how I can be more clear about it. GPX format does not support any shapes other than tracks (aka lines).
Ok. Now I got it. I will need to do more study on this topic to avoid asking silly questions in fiture. Thanks Anton. Highly appreciate your patience in guiding your community fans.
This is the final stop as he have reached his destination at this work place with not yet records of him leaving the geofence later today recorded by the hardware gps tracker in the car.
