When you upload an IGTV video, a separate tab for IGTV will appear on your profile from where you can manage your videos. There is also an IGTV tab on the Explore tab where you can explore IGTV videos of creators. IGTV videos can also be shared on the regular news feed. However, they cannot be viewed in full, but a preview can be shared that can last for a maximum of 60 seconds then you need to switch to IGTV to continue to watch the full video (the button will appear on the video to switch to IGTV when the preview is completed.)
