If you’re aInstagram user, there’s a good chance you’ve seen the option to “delete messages.” This is a great way to get rid of any old messages that you don’t want to see again. However, if you’re using an iPhone, there’s a better way to do this. To delete messages on Instagram for iPhone, first open the app and sign in. Then, under “Settings,” select “Privacy.” Next, under “Message History,” select “Delete.” Finally, tap on the checkbox next to “Delete all messages.” This will delete all of your messages from Instagram for iPhone.
