News feed not updating on facebook
Sharing your thoughts with your Facebook friends is instantaneous -- the second you click the “Post” button, your update appears on your Timeline and your friends' News Feeds.
You can select up to 30 people or Pages to see first.
Check your Internet connection and troubleshoot it if necessary.
If your Internet is working and you can access Facebook but it's not functioning the way it should, try logging out and then back in or even rebooting your computer.
If your settings are correct so that your feeds should be updating in a timely manner, you may have an Internet connection problem, or Facebook itself could be having an electronic hiccup.
Websites are not immune to the occasional operational issue, and sometimes some behind-the-scenes issue could affect the proper behavior of the site.
News Feed is the constantly updating list of stories in the middle of your home page.
