Problem writing files on Android AIR 30.0

Hi,

I have an error when I try to write a file on Android 8.0 on desktopDirectory (on AIR 30.0).

ANDROID 7.0:  It works without any problem.

ANDROID 8.0:  I tested on 2 different moviles and I get this error:  'Error #3001: File or directory access denied.'

NOTE 1:  On applicationStorageDirectory it works without any problem on both versions.

NOTE 2:  With AIR 28.0 it works without any problem on both versions.

NOTE 3:  When reading files it works without any problem on both versions.
