Connection lag

Before you add anything, please fix the ridiculous lag in Bedrock. It's almost unplayable online because you suddenly take damage or get set on fire in the Nether even if you're nowhere near lava. It causes so many deaths and a lot of frustration. The lag also makes it so that mining blocks doesn't actually mine the blocks so when the lag ends you're inside the blocks and you suffocate. This type of lag is not even uncommon, it's almost constant. You also can't eat or open chests or inventory. This needs immediate fixing.
