The Nintendo Switch edition of Minecraft has much trouble with crashes and lagging. In a multiplayer world, the lag goes up a lot and the game crashes and freezes consistently causing the game to be unplayable. 

In both, single player and multiplayer worlds, the game still crashes and freezes, as well as having insane amounts of chunk lag, block lag, slow loading, etc. Chunk Lag increases by a lot when boating or when flying using an elytra. The Game often completely freezes during auto saves as well. All of this in turn causes the game to be very difficult to manage and get through as these bugs are very consistent, they do not go away. I've deleted minecraft and reinstalled and it did nothing. I backed up my save data to the cloud, deleted my save data in the switch, deleted minecraft, reinstalled, downloaded my save data, and the issue persists. All of these issue have been continuous since the release of the 1.16 Nether Update. Please fix this, as the game is not playable.
