With older versions of MacOS X, one could transfer individual sequences via iTunes. It was terribly cumbersome, but possible.
Looks like in MacOS 10.15.5 files on the phone cannot be accessed from iTunes, but can be accessed from Finder.
Unfortunately, one cannot expand subdirectories, at most the “mapillary” directory is exposed (cannot attach a screenshot, getting “Access Denied”).
How could I easily transfer (move) individual sequences?
