All you said is correct.
The point is that Zeep app, paired to the band (no gps on band) is tracking.
This means the Zeep/google maps were able to use a location service which was working.
OSMAnd and Mapsme (using the OSM map) were not able.
Ok, i was trying to find out if the source of the problem could be to “relocate” my position on map, or if its the “location service”.
Thanks for answering
