Part 2: Reasons and Fixes: Edit/Unsend Messages Not Working iOS 16/17

Now we will go through six different methods that can fix unsend messages not working on iOS 16.

1. Update to iOS 16 on Recipient's iPhone

As this feature is exclusive to iOS 16 and later, and does not work when the recipient has an iPhone with iOS 15.7 or earlier. If you unsend a message from the conversation, the original message will appear in your iMessage app but a notification will come before you that the recipients will still see the deleted message.

When someone tell you that they still see the unsent message, the problem might not caused by you, so ask them if they have updated their iPhone to iOS 16 and later.

2. Use iMessages to Send Messages

This new "Edit and Undo Send" update has been introduced in iMessages only, which means you have to send the message to another iPhone. There is an easy tip to check. See if the messages you send are in blue or green bubble. The blue bubble is sent to iPhone while the green one is sent to non-Apple Devices.

3. Edit and Unsend within 15/2 Minutes

Another reason why edit and unsend messages is not working on iOS 16 is a certain time limit. You can edit a message for 15 minutes after you send it and can unsend a messages for up to 2 minutes. Each message is given 5 edits.

You have to take that opportunity in the first 15 or 2 minutes of sending text, or else things cannot be changed.

4. Restart iMessages App

Sometimes restarting is a good option for things to get refreshed if they are not working properly. When you cannot edit or undo send messages in iMessages, restart the app by swiping up and close it. And further restart your iPhone. Then tap on the iMessage app icon to use again.

5. Check Apple System Status

Another reason that unsend messages not working on iOS 16 is that the iMessages service could be down on the Apple server. To check if this is the case, go to Apple’s system status page.
