We continue to put people in control of their experiences in Messenger. All conversations between businesses and people must be initiated by the person receiving the messages, who can then mute or block the business at any time.

Also, an allowance to send one message after the 24 hour window is added.
"Each time a person responds to a business through one of the eligible actions listed in the chart below, the clock will reset." "This new policy allows businesses to re-engage an inactive user, while also providing people with more relevant and timely information that they requested," expalined dev team.
