fdroid scanner doesn't show details of problems or where to find them

I'm interested in finding out what the problems with a given APK are. So I run:

# ./fdroid/bin/fdroid scanner --exodus --verbose ./joplin-v2.8.1.apk

unfortunately, it doesn't tell me what the problems are or where to find details. Now I can't act on the report, because I don't know what needs fixing.
