Social media giant Instagram says it's looking into why some users have seen significant follower losses this week.
Celebrities like Ariana Grande and Selena Gomez were among the most affected, with Mashable reporting their drops at around two million each.
YouTuber James Charles says he lost up to 500,000 followers.
There was speculation Instagram had just carried out a 'purge' of "inauthentic" followers, but a statement from the Facebook-owned company suggests it could be something else.
"We're aware of an issue that is causing a change in account follower numbers for some people right now," Instagram wrote on its official Twitter account.
"We're working to resolve this as quickly as possible."
Some of our own Edge announcers have been affected by the glitch with Guy from The Edge Workday losing over 200 followers and both Meg and Randell losing over 400 followers.
