About 3 days ago, a new update to monday changed how Item Cards are displayed. In our account, I remember we had something activated on Monday Labs, to keep the item card showing as a pop-up on the center of the screen. That pop-up had the item columns displayed on the left side, and the card updates displayed on the right side.
This made it very easy to change status and other informatations about the card, as well as comment on the card to let other members know other important things.
With the new update, the item card opens on a sliding window, on the right side of the screen, and you can no longer see both the item columns and card updates at the same time.
