Okay so since the beginning of last year this issue has occured to a point where I can no longer play and enjoy minecraft. At first the issue began to start with the world generation time began to take much longer to open than it usually did and later the world itself, whether it's old or brand New, began to load in chunk much slower to a point where I'm stuck on the same chunk that I spawned in. Also whenever I tried moving into the next chunk there is an invisible wall that will not let me pass through. Ive tried deleting and re-downloading the game but the issue remains. I even tried it on a new device and the issue followed. I dont know if this is an issue with my microsoft account or a bug in the game itself.
