Not totally sure if this is related, but I had been using buttons to modify most recent row using the filter “[colName]= last([colName])”. However, recently, this filter fails to select only the most recent row and the button modifies all values in the column.
This can be seen on the “Untitled” page of this Coda doc: Buttons, tables, and filters
I believe the intended behavior of the button is to subtract 1 from the max Row ID. Now, the button seems to modify every row in the column instead.
