My friend (PS4) and me (Xbox) play Minecraft and we have had to grind our stuff back multiple times because of fame issues

My friend (ps4) and me (Xbox) have a Minecraft world together on his PS4 and we've encountered numerous problems some resulting in us having to grind back our netherite armour again and again. 

We've encountered; chunks not loading in correctly whilst flying with Elytras, chuck appearing to be loaded in but I fall through them and die in the void,  frame rates below 10 whilst fighting the wither which made us lose almost all of our items, spawn points randomly stop working which spawns us 3500 blocks away, fireworks not working properly with Elytras, inventory problems with selecting items (more of an annoyance than a problem), random cave noises, ghasts screaming way too loud well the amount of a ghasts in the first place, raid bell noises are almost deafening and the spawn locations of pilligers are sometimes underground which makes it a pain to find them. And just overall game lag even if we aren't doing anything that demanding. Even if you only have 2 players on one map if they are not in the same chunck there's is still lag present and it gets frustrating as Minecraft isn't a demanding game and shouldn't be performing this poorly on semi modern consoles, I love playing Minecraft especially with some crossplay support and I hate that these problems big or small still occur in the world's best-selling game please announce some fixes that help the game flow better because right now it seems every update adds on to the growing number of problems that don't get attention or that seem to not. Please fix this game I understand that it's alot easier than said but atleast make a tweet that yous are working on it, sorry to complain but it feels like the game is trying to mess me up in everyway, thank you in advance
