There are many reasons why Instagram pictures not loading. Some of them are:
- Your internet connection is slow.
- You have a limited data plan.
- The page is down or having a maintenance problem.
- You have recently updated your Instagram app and it’s not yet compatible with your device or operating system version, etc…
- Your device has an old version of Android or iOS (like iPhone 4S, iPod Touch 5G).
- Your device has no enough RAM to access the app properly.
