I have Tumbleweed and just received the 25.08 update.
It seems the Create New Folder menu item no longer works when selecting it off an existing folder as the popup never displays. If you right-click empty space (root of whatever view), the popup will show up and work. Ctrl+Shift+N also works because of the long existing bug where keyboard shortcuts (that, CTRL+V, etc.) always operate at the root of the current view instead of the highlighted selection.
Anyone else experience this issue? Is it a problem with Tumbleweeds build or with 25.08?
