I regularly receive notifications in Facebook Messenger about the anniversary of my friendship (amiversaire in the French version) with a friend. Messages like
you have been friends with [friend] since [date]
(my own translation from French). The message also appears in the private chat with that friend. This is annoying since I have many friends and I am receiving daily a lot of undesired notifications.
Is there a way to turn off these notifications?
I tried to google it but all results are about notifications of friends' anniversary, which I want to keep.
