A bug is causing Instagram users to see their feed as black.

A bug has been affecting the Instagram app, causing users to see their feed as black. The issue was first reported by Twitter user @kylethefinn, who shared a screenshot of his feed on October 26th. The app reportedly only shows black for about 15 seconds before returning to normal, but it can be very jarring for those who experience it.

The Verge confirmed that the bug is affecting both Android and iOS versions of the app. It’s not clear what’s causing the issue, but many are speculating that it’s related to a previous update in which Instagram added a dark mode option. A spokesperson for Instagram said that they are aware of the issue and are working on a fix.
