Since Bedrock 1.20.30 update (PS4), the game has been almost unplayable due to frequent periods of lag. It was fine before this update. Issues include:

• arrows not firing, or firing after a delay, then flying through the air in slow motion
• mobs flying back in slow motion after being hit
• mobs/villagers walking around in slow motion
• block breaking visualisation lag when mining
• doors not closing, or closing after delay
• villagers sleeping next to their bed, not on it (perhaps this is an unrelated bug?)
• (FYI: general player movement is fine/no lag)

I wonder if this is relating to how much of the world has been explored? I've defeated the end dragon, but I haven't actually explored much of the overworld (maybe 1000 blocks out from spawn? Mostly in 1 direction).
