Some users have been complaining that Facebook Messenger stopped working for them. They say that the app is crashing or not opening. When users try to open it, it just disappears, even though it appears to be running when the App Switcher is opened. They have further said that the Messenger app was working before the recent iOS update.

When affected users open the App Switcher (which can be opened by swiping up) to see the recently used apps, Facebook Messenger shows up there with a blank white screen and a Meta logo in the middle.

Facebook Messenger, now known as just Messenger, is a popular messaging app used by many iPhone 18 Pro users. If you are having issues, you can try the following:

Update the app

Ensure that you are using the latest version of the Messenger app:

  1. Open the App Store on your iPhone.
  2. From the options at the bottom, tap Search.
  3. In the search field, type Messenger and hit Search.
  4. From the results, find the Messenger app. If the app says Open, this means that there is no update and you are running the latest version. If it says Update, it means there is an update. Tap Update.

You should note that if you have turned on automatic app updates, they don’t occur immediately. You should still follow the steps above to update.

Update your iPhone 18 Pro

We know that your Messenger problem started after a recent update. Please ensure that you have the latest iOS version. On your iPhone, go to Settings > General > Software Update. If there is a new version, you will see it there. Then tap the Update Now button and follow the onscreen instructions.

Restart your iPhone 18 Pro

This may be something to do with your iPhone. Restarting may put everything back into a working state. To restart your iPhone, follow these steps:

  1. Press and hold the Side and either of the Volume buttons (Up or Down).

  2. Keep pressing the buttons until you see the power-off slider. Then, release the buttons.
  3. Drag the slider.

Wait until your iPhone powers off, which may take several seconds. Then press and hold the Side button again. Release the Side button when you see the Apple logo.

Change the text size

It seems that this fixed the problem for many. These steps will slightly change the font size on your iPhone 18 Pro.

  1. Open Settings and tap Appearance.
  2. Tap Text Size.
  3. You will see a slider. Drag the slider slightly to the left to make the fonts a little smaller.
  4. Exit Settings and now try to load Messenger.
