Part 1: What does the LINE Messages Delayed Mean

Unfortunately, the LINE messages delayed issue may take different forms for different people. One person may experience one kind of delay, while others may face a different one.

1. LINE messages delayed sending

One of the common complaints people have is the LINE app not sending messages. In this kind of delay, your messages won’t be delivered to the receiver instantly. You may have typed and sent the message from your end, but it won’t be delivered until later.

2. Messages delayed receiving on LINE

The second form of this issue is the LINE app not receiving messages. In this type of delay, you won’t receive the incoming messages on time. The sender may have sent the message early on, but you may receive it after a few hours.

3. LINE notification delayed

Last but not least, you may face a LINE notification delay. In this type of delay, you may not receive a notification for incoming messages. Hence, you won’t be able to receive new messages until you have opened the app. When people face this type of delay, they may keep scratching their heads while asking the question, “Why do I only receive messages once I open the app?”

Part 2: Why is LINE Messages Delayed

You may face the LINE messages delayed issue due to one of the several possible reasons. Here are some of the most common ones.

  • You may have a slow or unstable internet connection.
  • You may have turned on your phone’s battery saver, which might be stopping LINE from running in the background.
  • You may have turned off notifications for the LINE app.
  • You have turned off Background App Refresh for LINE on your iPhone.

Part 3: How to Fix LINE Messages Delayed

With the causes out of the way, let’s talk about some possible fixes to the LINE messages delayed issue.

1. Turn on LINE Notifications

One of the most common reasons for the LINE messages delayed issue is that you may have turned off its notifications accidentally. You see, you won’t receive notifications if you have turned them off.

Here’s how you can confirm whether your LINE notifications are turned on.

  • Open the LINE app on your phone. Go to the home tab and tap Settings.
  • Then select Notification Settings.

2. Change Network Connection

You may face the LINE messages delayed issue if you have a slow or unstable internet connection. That’s because the application uses your device’s active internet connection to sync with the server to send and receive your messages. If you have a slow or laggy internet connection, the app may not be able to contact its servers effectively.

To troubleshoot the cause of the issue, try a different network connection. If the issue doesn’t go away even after you’ve changed your network connection, proceed to the next section.

3. Offload and Reinstall LINE

Offloading is a nice feature on iOS that lets you keep an app’s data while reinstalling it. If you’re facing the LINE messages delayed issue even when your device has a stable internet connection and notifications turned on, try offloading and reinstalling the app.

To do that, go to your iPhone’s Settings > General > iPhone Storage > LINE > Offload App. After you’ve offloaded the app, simply uninstall it and reinstall it from the App Store.

4. Clear App's and Device's Storage

The last resort to solving the LINE messages delayed issue is to clear the device storage.

To do that on your Android phone, go to Settings > Apps > LINE > Clear Storage. Or you can also delete some photos, apps or videos to free more device storage space.

Note: you will lose your chat history if you haven’t backed it up using the cloud.

If you’re on an iPhone, there’s no simple way to clear an app’s storage. Hence, you will have to uninstall the app and install it again from the App Store. But you can free up the device's storage by deleting files.
