Sony shares slide amid gamer backlash over 'Fortnite' PlayStation 4 and Nintendo Switch issue

Players have expressed anger over a so-called cross-play issue with "Fortnite" that doesn't allow them to use an account associated with a Sony PlayStation 4 to play the game on the Nintendo Switch. This means progress and in-game purchases on "Fortnite" on the PS4 can't be carried over to the Switch. Sony shares fell 2 percent.
