Shopping carts have been a fun addition to Fortnite: Battle Royale, but they've also proven to be a problematic one. Epic Games has had to disable them a number of times due to problems that have arisen, and that's the case once again.

During E3, Fortnite: Battle Royale was released on Switch, joining the existing PC, PS4, Xbox One, and iPhone versions. Fortnite Mobile is also on the way to Android, although a release date for that version has not yet been announced.
