How are you trying to access?
I understand you are having trouble using Mixplorer, and that would not be my choice for something like this.
From a terminal, without asserting privilege,
Code:
ls -dl /sdcard
ls -dl /sdcard/
ls -dl /sdcard/Android
I expect the first one to show that "/sdcard" is a link.
For me, the next two show "drwxrwx--- root everybody". Maybe I'm reading too much into it, but I assume everybody is in the "everybody" group.
I know the joys of SELinix make it possible for the SE context to block access when the naive permissions seem to allow it, but we have to start somewhere.
