Share Play feature, Sony's online pass-the-controller multiplayer service. Namely, it appears FIFA 15 is giving players fits, as visiting players are unable to view the footage shown on the host's console. Rather, one half of the Share Play tandem sees the screen above, which says, "Viewing the game screen that the host is currently playing is not allowed due to content restrictions in your country or region."
In our tests between two US-based PS4 players this morning, the Share Play visitor was unable to view game footage on four separate occasions: In FIFA 15, WWE 2K15, Guacamelee and Middle-earth: Shadow of Mordor. Share Play for FIFA 15 was functional once we tested the service with our UK-based editor, Sinan Kubba (albeit with some bouts of lowered resolution and frame-dropping). However, it appears the error message being displayed is entirely inaccurate, as PlayStation noted on Twitter, adding that the support team is investigating the issues.
Eurogamer's big list of Share Play-functioning games notes that FIFA 15 "works fine," so your mileage (or kilometer-age in this case) may vary at the moment. Share Play arrived in October as part of the PS4's version 2.0 update, which itself caused a number of other issues for players. Sony issued another update just this week, version 2.02, to rectify some of the console's lingering problems. We've reached out to Sony to find out what might be causing the hiccups with Share Play and which games are affected.
