Update Facebook Messenger

First of all, make sure to close the Messenger app and open up your Google Play or App Store application. This guide will be showcased on an iPhone, but you can follow along using your Android device. Here, look up Messenger and ensure that you are using the most up-to-date version of the app.

Select Correct Messenger Account

When this is done, re-open Messenger. From here, tap on your profile picture icon on the top left of your screen. Scroll down and tap on Switch account.

This allows you to choose the account you want to use your Messenger app with.

Clear Messenger App Cache

Next, to prevent any potential login problems or errors, close Messenger and open up your device settings. On your iOS device, scroll down and tap on General. On Android, you can directly navigate to your Storage settings. Tap on iPhone Storage.
