On a test site, and on indico.global, if I go to a contribution page, at the top right, I see a button to “Add this contribution to your timetable”.

However, on a separate server running 3.3.12, the button is missing. Also, the “My Timetable” menu item isn’t there when I try the customize menu feature.

I cannot see how this was removed. There doesn’t appear to exist a setting for it either in the webUI or in indico.conf, As far as I know, it should be there by default. It’s a great feature and I would really like it back. Any guidance would be much appreciated.
