Helen, the issue is that Sync is not updated with the new Lollipop APIs that allow writing to sd card. In 5.0, a new intent was added that would allow a user to give any app write access to any folder on shared storage (i.e. sd card). More information and documentation can be found here: https://groups.google.com/forum/#!topic/android-platform/PkLYIERoJvo and here: http://developer.android.com/reference/android/support/v4/provider/DocumentFile.html I'm sure the developers are already aware of these new APIs, but we'd like a higher priority placed on implementing them so we can better manage our storage on our devices with Android 5+. Thanks!
