If you’re like most people, you probably use the Playstation App to manage your games and social media. But there are a few things you can do to delete messages from the app – even if they’ve been sent to you by someone else. To delete messages from the Playstation App, open the App and sign in with your Playstation account. Then, under “My Messages,” select “Delete.” You’ll be asked to confirm this action before deleting the message. If you’ve received a message from someone else on the Playstation App but don’t want it stored on your account, select “Notifications” in the top left corner of the App and select “Delete.” This will deletes all messages that have been sent to you since your last login.
