Messenger is a free app for iPhone and Android that lets you send and receive messages. But sometimes, when you try to delete a message, it says that you don’t have permission to do so. This is because Messenger is part of the Facebook app, and Facebook uses your data to track how often you use Messenger and what kind of messages you send. If Facebook found out that you were deleting messages on Messenger, it could potentially see your data and contact information (like your name and address) and sell it to other companies. To fix this, just go into the settings of Messenger on both devices and set up a password for yourself. Then, when you try to delete a message, it will say that you don’t have permission to do so but will still let you proceed.
