Why can’t I open gpx files with garmin connect in IOS 13? Deleted and installed the app and it started working, after one day it didn’t work anymore and now I can’t open gpx anymore, even if I reinstall the app.

This may not be your problem, but I have this issue when the file name for the GPX is not the same as in the <name> tag inside the file.
