Facebook Message Sent But Not Delivered - How to Fix

I messaged someone on Facebook and it’s been sent, not delivered. The problem is, the person has gone online. What is going on? Any help would be appreciated.

Facebook is one of the most popular social media platforms that is used by millions of users all over the world. People enjoy great conveniences but also face some errors when sending or receiving messages. A lot of users complain that their Facebook messages are sent but not delivered. If you find yourself in this situation, it is easy to think that your friend on Facebook has blocked you. While that could be a reason why your Facebook messages remain undelivered, there are several other reasons why your messages won’t go through.

In this article we are going to be looking at some of these reasons. But even more importantly, we will show you how to fix Facebook message not working on iPhone. Let’s check out.

Part 1. Why Facebook Message Sent But Not Delivered

As mentioned above, there are many different reasons why your messages are sent but not delivered even your friend is seen to be active on Facebook. In this part, we’ve gathered several obvious reasons why this problem occur. Some of the most common ones include the following:

  • The recipient may have ignored the message you’ve sent.
  • They may also have quickly deleted the messages without reading it or they may have read it on the status bar and then deleted it
  • The recipient could also have marked the message as spam.
  • They may also not be logged into Messenger, but they are using Facebook.
  • The message is in the Connection Requests or Messages Request list and it is not yet approved.

Part 2. How to Tell If Someone Blocked You on Facebook

The Facebook messages sent but not delivered problem often lead people to think that they have been blocked by the recipients on Facebook. Well, there is no clear clues that confirms you’ve been blocked, the following are just some of the signs you can check to figure out for sure:

  • Try to check your friends list. If the person have disappeared from your friends list, it might means that he/she has blocked you on Facebook.
  • Try to search for their name on Facebook. If you are unable to find it, it means that the person has blocked you. But it is also possible that the person has set up their privacy settings so that they cannot be found.
  • Try to create a post and tag that person in this post. If you failed to do that, it is a signal that the person has blocked you.
  • Try to create an event and invite that person to this event. If you can’t invite the person, it means that he/she has unfriend you.
  • If you have a mutual friend, look at their friends list. If your friend doesn’t come up, then it is very likely that they have blocked you
  • Search for an old conversation on Messenger and click on it. If the users’ photo appears but their name is in bold and you can’t click on it, then they have blocked you.
