Button links not available in editor

on a standard button, the link isnt editable in the editor

our client should be able to change the link on a button in the editor - basic bug seems not to have been addressed since i notice it was raised 3 yrs ago…

please advise why this may not be working


Here is my public share link: LINK
(how to access public share link)

i take it back, it is a styled link box, not a standard button - but the link isnt editable in the editor
