unable to open gpx files via Files app
I'm using Nextcloud 22.2.0 (as a Docker image) and installed GpxPod 4.2.8. I'm aware of #44 (closed) and also followed the instructions for registering the mime type in order to be able to directly open a gpx file via the Files app. But still, when opening a gpx file, all I get is a new GpxPod tab with a blank world map and the red message There is no directory in your list
in the options pane. I've tried this with current stable versions of Firefox and Chrome. What could be missing to make this work?
(Note: Opening the same file after manually adding the folder in GpxPod would work. So the file itself is fine.)
