I'm on macOS Catalina 10.15.6 19G2021 x86_64.
I was trying to create a signature with Preview.app and the MacBook's built-in camera, when I clicked on
Done button, the captured signature wasn't saved.
I tried to restart Preview.app, reopen the document and open another document and it still didn't work.
Is it a bug? What should I do? Thanks!
