When you click on a non-shared password, there are two buttons shown at the bottom middle of the screen; Edit and Clone.
However, when a shared password is click on, only the Edit button shows up.
You can still right click and select clone to get the clone function to work on both shared and non-shared passwords.
Please fix the clone button issue on Windows App v1.24.6.
NOTE: Just checked the Chrome extension v1.48.1, and the same issue happens on that. There is no “Clone item” option shown for shared items.
