Why aren't video views showing up on Instagram?
It may take some time before a video view shows up. If video views aren't showing up, try checking back later. Note that you can't see the number of video views if your video is part of a post with multiple photos and videos.
Also, keep in mind that video views only include views from within the Instagram app, and not from other places like an embedded post or from a browser. If your account is set to private, you may not see the video view count until your video has reached a certain number of video views.
Video view counts will only show up on videos that were added after November 19, 2015.
