We are actively investigating issues impacting players' ability to sign in to Destiny on all platforms. Until resolved, players may experience disconnects or be unable to sign in.
Player invite e.g. on PS4 is way too complex and takes too long. Sending an external invite which seems to be handled by the PS4 OS/PSN breaks the game experience. A window pops up, the screen loads, the player nickname has to load, I have to select the send button and wait, wait, wait too long. This system is ok if another player is not ingame, but if he is in the game I should be able to invite someone with a press of a button.
