Make sure the NotyFeedbackMessage web block is added to the layout blocks in use

The feedback messages will only be displayed until you reach the maximum number of messages visible on the screen.

After that, messages will remain in a queue and will be displayed after the previous ones are removed (either manually by click or after the message timeout)

When "Close All Visible on display" is active all visible messages will be closed and the new one will be displayed alongside other messages in the queue.
