One track export method allows change of file name, other method doesn't
- From list of tracks > tap track > tap ^ > tap Export - the file name can be altered before the export is performed.
- From list of tracks > long tap track > tap Export - the file name is not displayed, and therefore can't be altered before the export is performed.
The 2nd method allows multiple tracks to be exported simultaneously, so in situations where multiple tracks have been selected it clearly makes sense that change of file name is not possible. My suggestion: when only 1 track is selected, always use the Data Export dialog of method 1 so that the file name can optionally be altered.
