If you're having troubles opening notebooks, please make sure that, from a SWAN terminal, you remove this temporary directory in your CERNBox: ~/.local/share/jupyter. The latest deployment of SWAN implements an optimisation which makes it redundant.
When you open the Sharing Panel on a already shared project, you will notice that you no longer see the names of the people you shared with, only the usernames.
If some element in the UI is not working as expected (i.e if clicking in the share button doesn't open the share dialog), it might be caused by your adblocker. Try disabling it for SWAN to see if it's the cause.
