Two days ago, I recently changed my Bungie.net account name in order to match my new username on the PS, but when I logged into Destiny 2 today on the PS4, after the character selection screen it went black, but the background music was still playing. After a few minutes, it said "You have lost connection to Destiny servers. Your permissions to access online multiplayer gameplay may have changed or your profile may have been signed in elsewhere". I don't know if it is because I changed my account name on Bungie.net or if it is a PS4 server issue. I tried logging out of my PSN and turning off the PS4 and logging back in, but the same issue happens when I log into Destiny 2.
