The second reason is that you may have deleted the post, or it may have been removed by Instagram for a policy violation. Also, if you’ve recently changed your username, some of your old posts may not be associated with your new username. Furthermore, it could be that your feed is not updated and you can only read the posts and stories that were previously displayed on your feed. To solve this, you may need to check your internet status from the path below on your Windows desktop if you are logged in. To fix this problem, go to your profile, tap on three horizontal lines at the top-right and go to Settings > Privacy > Activity Status. Here you can see if you have turned off the Activity status or not. If yes, then turn it on by tapping on the toggle button to turn it into green. RELATED: How To Unhide Likes On Instagram
