I can't send messages in some or all of my chats

You may have been restricted from sending messages for violating our Terms and Conditions of Use.

Temporary restrictions generally last from one hour to up to seven days; however you may be restricted for longer depending on the nature of the violation.

You will be able to send messages again once the restriction is lifted, so try again after a few days.

Note: We are unable to respond to individual inquiries about the restriction period.

The main types of activity that constitute violations are as follows:

• Posting content that is violent, obscene, or otherwise deemed unacceptable

• Exchanging personal information (e.g. phone number, address, LINE ID), or continually inviting or soliciting others to meet in person

• Engaging in unlawful acts, such as the illegal trading of banned substances, stocks, etc.

• Planning or sending invitations to inappropriate meetings or assemblies that involve minors

For more details, refer to the Standards regarding posts on LINE.

Please understand that we are unable to respond to individual inquiries about which terms were violated.

If you don't remember doing anything that could have violated the Terms and Conditions of Use, contact us via this Inquiry Form and we will look into the matter.

I can't send/receive chat messages

If you're experiencing issues sending or receiving chat messages, check the information below.

Issues sending chat messages

There may be a network connection issue. Check your connection and try again.

When a message is sent successfully, the time it was sent will appear next to it. If someone still cannot see a message that was sent successfully, it may be due to one of the following reasons.

• If the other user hasn't added you as a friend, they may have the Filter messages setting turned ON.
Note: If this is the case, you need to have them tap the Home tab > Settings > Privacy, turn Filter messages OFF, and add you as a friend.
• The other user's LINE account may have changed (e.g. due to changing devices).
Note: We can't provide details about the state of another user's LINE account for security reasons.
• Your use of the service may have been suspended due to violating our Terms and Conditions of Use.

Issues receiving chat messages

• There may be a network connection issue. Check your connection and try again.
• You may have the Filter messages setting turned ON. If so, you won't receive chat messages from users that you haven't added as friends.
• Your use of the service may have been suspended due to violating our Terms and Conditions of Use.

If the issue persists, try the following troubleshooting tips.

• Update the LINE app here.

• Update your OS to the latest version.

• Close all running apps.

• Restart your device.

• Delete any unnecessary apps and data on your device.

• Check or disable any web limiting or filtering services you may have in place.

• Go back to your chat list and reopen the chat you're having issues with.

• Reinstall the LINE app. (For details, see this Help article.)

Please note that sometimes it may take a while for a chat message to show up after you receive the notification.

Chat list information is incorrect/My chat history differs from what others see

This happens when your device cannot auto-sync with our servers for some reason. Update LINE to the latest version here, then restart your device.

If you've updated LINE and restarted the app as well as your device but are still experiencing the issue, check the information below for the issue you're having.

Your chat list information is incorrect

Affected information: Chat list
E.g. A chat no longer appears even though you did not delete it.

Try manually syncing your chat list information yourself by tapping this link from the smartphone that you use with LINE.
Note: Do not sync your information multiple times in a row.

Your chat history differs from what others see

Affected information: Chat history
E.g. The content of your chat is different from your friend's chat.

Try manually syncing your chat history yourself by tapping this link from the smartphone that you use with LINE.
Note:
- Do not sync your information multiple times in a row.
- You can select up to ten chats in your chat list each time you manually sync your chat history.
- Chat messages can no longer be synced manually after a certain period of time has passed. (We are unable to provide details about the exact length of time.)

Be advised:
Back up your chat history before manually syncing it. If your chat history is encrypted and you don't back it up before doing a manual sync, you will no longer be able to see your chat messages.
