not sure its screenshot-able, however to be more specific it happens under the following circumstances:
View Details of Table A.
Table A contains “Related Table B” with an inline view.
Table B_inline is a Card view.
So, viewing Table A_details includes the inline view Table B_inline which presents a card for each related row in Table B. The three button menu has 2 actions: Edit, Delete. Delete works, but Edit will either do nothing, or in some cases show the Table B_details view, if it exists.
I have confirmed that I only have the system generated Edit Actions, and that the correct action is assigned in the menu. I created a second Edit action for Table B and it didn’t work either.
I did recently create 2 table slices that are read-only to suppress the ‘new’ option in drop downs. One of these is a slice of Table B, but the related reference in question points to the original, r/w-able version of Table B.
