I tried to import a GPX file with some waypoints (POIs) from hochgehberge.de. With Explore Web, it silently fails without any message. With Explore on Andoid, it tells me that the import failed (no more information). Since I can import the file in other sites (wikiloc, komoot) and programs (QMapShack), I guess the file is technically ok. Is there a place (this one?) to report such problems to Garmin?
