When checking or unchecking the checkbox on an object store container, nothing happens. This is only configurable when creating the container.
It also doesn't seem to work using the swift command-line tool. I'm going to figure out why this isn't working. I'll keep you up to date!
It appears to be a more complicated issue than we hoped. We'll keep you informed of our progress.
This issue has been resolved. You can now make a container public or private.
