No, Messenger does not delete messages on both sides.
To delete Facebook messages on both sides, you need to log into your account and access the chat history. You can also delete your messages from within the chat window.
You can delete Facebook messages on both sides by deleting the message from your inbox, then opening the chat window with the person you sent it to. From there, you can click the three dots in the top right corner of the screen and select Delete All Messages.
If you are trying to find out if someone has deleted your conversation on Facebook, the only way to know for sure is if they tell you.
To unsend a message on Messenger, tap and hold the message you want to remove. A pop-up menu will appear with an option to Delete or Unsend. Tap Unsend and the message will be removed from your chat.
Vanish mode on Facebook Messenger is a feature that allows you to hide your chat from the person you’re chatting with. It’s useful for situations where you don’t want the other person to see your messages, such as when you’re breaking up with someone or if you suspect they may be using your account without your permission.
The conversation may have been deleted by the other person, or it may have expired.
I’m not sure if Vanish mode is a thing.
Vanish mode is a feature that can be applied to any individual post on Facebook. It works by removing the post from your timeline and hiding it from other people’s timelines. The only way that they will be able to see the post is if they go to your profile and look at posts you’ve shared with them.
If you are using the Facebook Messenger app on your Android or iOS device, then go to Settings > Chat settings > Delete messages. If you are using the Windows 10 app, go to Settings > Chat settings > Clear chat history.
