Several days ago we lost the ability to manage the sharing permissions in large Shared folders.
Folder with 30 items or less still function fine.
Larger folders, we right click the folder and choose Manage. Then any existing account in that dialog that we hit the Wrench icon beside and the background goes grey and nothing happens.
If we close the foreground window with cancel, we can see the infinite spinner.
It never goes away.
We've followed the steps to flush browser and lastpass cache, refreshed sites, logged out and in.
This occurs across multiple admin's PC's and Mac's, and is the same in Chrome, IE, Edge. In the plugin or on Lastpass.com
