Same height Cards (Auto layout)

I am trying to get the cards grouped in Auto layout and to have automatically the same height (following the tallest card).
Here what I’ve done so far…
I’ve only few hours of experience, so I apology in advance in case this is a silly question.

Seems not the solution for me… I’ve posted my file here… it seems following your suggestion, but it fails… any suggestion :upside_down_face:
