Live broadcasting with Instagram is so amazing and all you need to do is access the app’s camera interface. Follow the steps I will tell you. Let’s go!
1.Launch the Instagram app on your iPhone.
2.Make sure you’re in the Home section of the app which is your Instagram feed. Here, either tap on “Your Story” or the “+” icon at the top-right icon of the screen to open the camera.
3.Depending on what you tapped on in the last step, you may be in the Post or Story section of the camera. Swipe left on it to switch between Instagram features and you’ll find LIVE on the extreme right.
4.Now, simply press the LIVE shutter button as shown in the screenshot below to begin the broadcast.
It’s really awesome. Now you can just start to enjoy your live-streaming!
The second you go live, your live broadcast will show up at the top of your followers’ Instagram feeds along with other Stories. You’ll be able to see the people who join in to watch your broadcast. Once you end the broadcast, you’ll have the option to save it to your camera roll if you want to watch it later.
