Changes to how Instagram content will appear in the app’s feed have sparked a backlash among some of its users.
The app plans to switch to “algorithmic timelines” – sorting posts according to users’ interests – rather continuing to list them chronologically.
Celebrity posters, who are worried their photos may no longer be seen by as many people, have urged their followers to “turn on notifications”.
But Instagram said there was no reason to panic.
“We’re listening and we assure you nothing is changing with your feed right now,” the photo-sharing app said in a tweet.
The shift will bring the app in line with the way news feeds are ordered on Facebook, which is owned by the same company.
