I cannot download my map track after my running session
Are you trying to export your run activity? Are you trying to just view the track on the map? Something else? On the app? You should use Garmin Connect Web.for exporting the activity as a FIT or GPX file.

Then I assume you're doing the export from Garmin Connect Web, not Android (this forum).
Can you attach your exported FIT file here? You'll need to first zip it, if it isn't already zipped. Then maybe we can see what's going on.
