Minecraft Bedrock Lag

After the release of 1.19 version for a lot of players, including me, Minecraft Bedrock became unplayable. It lags so much, takes several minutes to open worlds, destroy/place blocks and kill mobs. Chunks are so slow to load and it’s impossible to explore the new biomes. It’s not a device problem and I talked to some players and they have the same problem. It’s a question of optimization… please fix this as soon as you can.
