In competition with Whatsapp, Instagram users have just been treated to a new way of sending messages. Now you can send audio messages too in Instagram DMs. If you still cannot see this option, just head to the App Store on your device and check for the latest app updates.
How can you send a voice recording in DM?
Simply just press the voice recording symbol to record your greeting.
Once pressed you will be able to see the voice memo appear as part of your chat history.
