GPX Import failed

Hi,

I just tried to import a GPX-file that contains a few waypoints. The file was created with Garmin BaseCamp and modified and converted with Routeconverter and saved a GPX1.1. When I send this file to my Tablet (Android 10) and try to open it with Navigator it should be imported. But I get an error "Can't import colour scheme" andnothing is imported. :-(

I think there is no colour sheme included in GPX-Files or am I wrong?

Here is the header of the my GPX file:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<gpx xmlns:gpxtpx1="http://www.garmin.com/xmlschemas/TrackPointExtension/v1" xmlns="http://www.topografix.com/GPX/1/1" xmlns:trp="http://www.garmin.com/xmlschemas/TripExtensions/v1" xmlns:gpxx="http://www.garmin.com/xmlschemas/GpxExtensions/v3" xmlns:gpxtpx="http://www.garmin.com/xmlschemas/TrackPointExtension/v2" version="1.1" creator="RouteConverter 2.31.2">
    <metadata>
        <time>2022-05-25T09:42:21.872Z</time>
    </metadata>
    <rte>

An other file with the same header works, but some didn't.

In earlier versions of Navigator the import works perfect and fast.

Any help?

Regards

Michael
