Sometimes you may get an error like ‘Facebook App Session Expired’ when you are on your Facebook page, and it also says that you need to log in again. Sessions are usually used to keep you logged in to your preferred sites and services. Sessions were developed to time out so that someone else cannot get access to your sensitive data. Facebook also uses sessions in the same way but typically reserves the sessions for third-party services and apps to keep your Facebook account safe. It also saves the battery life of your mobile phone.

Facebook uses sessions to validate that your account is within its service. It could be when you play some games or using the Facebook app. The sessions rely on cached information. When the cache is cleared, the session ends.
Here are some steps if you face the Facebook App Session Expired error:
The first thing for you to try is to sign out of Facebook and sign back in.
Clear the browsing data for your browser. Once you do this, the issue should be resolved. If not, perhaps one of the browser extensions is creating a problem, so you should remove the extension and try using Facebook again.
If you are using the Facebook app and get this error, navigate to your app store (Google Play Store or App Store) and look for a new version of the Facebook app. If there is, download it.
If this doesn’t make any difference, you may reinstall the app. Go to the home screen of your device, tap and hold the Facebook app icon and if you are using iPhone, click on the X and then Delete, and if you are using Android, click on Uninstall. Head over to the app store, download, and install the app again.
