Google has released an update to the Files application (DocumentsUI). This results in an inability to select Android/(data|obb) folders to grant permission (the Files application show wrong location).

To rollback this update you need to go: phone settings > Apps > App management / All apps > Files (application name depends of your phone locale) > Uninstall updates (may be in menu)

To display the list of files and work with files and archives, ZArchiver requires the "All file access" permission.

To grant access, you must activate the switch in the window.

Samsung devices have a different permission dialog layout.

To access a data in the subfolder of Android/data folder, explicit permission is required to access them.
