Sometimes Instagram couldn't refresh the feeds properly. At that time we were confused about how to tackle this situation. To check if any issue persists from the server side visit these two websites DownDetector or IsitDownRightNow. That shows the real-time updates and server outages and which website is down or up. This can show up on many of the websites at the same time, you can check even other websites on this platform. However, you can also check your connection if the issues continuously persist.
