Apple is splitting its App Store division in half, according to a report from Bloomberg. While one group of employees will run the App Store, the other will manage its approach to alternative marketplaces that have started opening up in the European Union.

As part of the change, App Store vice president Matt Fischer will leave the company after more than a decade in the role. “This has been on my mind for some time, and as we are also reorganizing the team to better manage new challenges and opportunities, now is the right moment to pass the baton to two outstanding leaders on my team,” Fischer writes in an email to employees seen by Bloomberg. Fischer has also posted the email on LinkedIn.

Now, Apple senior director Carson Oliver will reportedly oversee the App Store division, while Ann Thai, a product director at the company, will head up the group that tackles alternative distribution. App Store chief Phil Schiller will oversee both divisions. The Verge reached out to Apple with a request for comment but didn’t immediately hear back.

Update, August 21st: Added a link to Fischer’s full email sent to staff.
