Command-Z doesn’t work when I try to undo an edit of a note, and these are the only options in the ‘Edit’ menu bar which other forums have recommended
I’m on a Mac running the latest version.
That doesn’t look like Anki. Are you using the official apps from https://apps.ankiweb.net/ ?
The “Edit Current” window you’re in doesn’t have its own menu bar, so that “Edit” menu appears to be provided by macOS, not by Anki. Whenever you see the Edit menu referenced with regard to Anki, it should mean the menu bar in the main Anki window.
