Facebook’s Messenger has its notification where the user’s new friend is connected to Messenger, it will message the user and has a “Say hi with a wave” alert.
A number of users are against this notification according to TechCrunch because users already know that they were connected to their new friend so Messenger should not tell them about it.
“We’ve found that many people have appreciated getting a notification when a friend joins Messenger. That said, we are working to make these notifications even more useful by employing machine learning to send fewer of them over time to people who enjoy getting them less. We appreciate all and any feedback that people send our way, so please keep it coming because it helps us make the product better.” Facebook’s spokesperson told TechCrunch.
Facebook added that this notification will be sent only to users who have used the app often in the past.
