Hi there!
I just reinstalled Apex on my PS4 Pro for the new season and I'm unable to play. I've tried to get into matches twice today. First time I was disconnected after a couple minutes into a match, and was greeted with the code:leaf error prompt preventing me from playing anymore.
The second time I tried a few hours later my game was lagging so bad I ended up dying & losing the match, then got stuck in that match trying to return to the lobby, with the prompt stating "Connecting to Lobby" indefinitely. I then restarted the game and got the code: leaf error again preventing me from ever getting fully into the game.
