I've just updated to 1.18 on my PS4 and there is so much lag in the mechanics of the game, opening chests, doors, gates, interacting with villagers, killing mobs, using fireworks to fly. So much just isn't working. I use the word lag as sometimes, after about a minute, a few sound effects play and then the system seems to have caught up again, only to lag one more but most of the time, things are just seeming to not work.

Is there anything I can do to get rid of these issues?
