It seems players on the PlayStation 4 have been having performance issues. Blizzard have found the reason and fixed it, but are now waiting on verification from the platform to deploy the patch. It should be coming tomorrow or on Monday.
Hello all –
We have been monitoring the issues that players have been experiencing particularly with PS4 users. We have a patch currently submitted over for verification and are awaiting approval on this.
We anticipate this to happen either tomorrow or at the very latest on Monday. We apologize for the extra performance issues players are experiencing with this and will provide an update once we hear back.
