Mail App keyboards shortcuts not working?

None of the shortcuts mentioned in the user documentation of the mail app seem to work : mail/ at main 路 nextcloud/mail 路 GitHub

Is that just me, or is that a bug?

Works over here: I just used del, arrow left, array right and s.

Ah, I see. I was trying the vim shortcuts j/k but these don鈥檛 seem to work.
Also the archive shortcut isn鈥檛 working.

You need Mail 3.0 for the archive shortcut.
