I am experiencing an issue since few days ago with the locus map addon for Garmin. Xiaomi Redmi note 11 and Fenix 7.
Every time I try to export a GPX file from locusmapt to Garmin, it shows a red screen saying invalid fit file.
If I export fit or gpx file to the storage and then import to my watch with iq map receiver or gimporter it works. So it shouldn't be a problem for the gpx file itself. The problem is in the process of sending the file to the watch via locus add-on
