Ever since the 1.16.200 update, Minecraft Bedrock has had serious lag issues I've noticed ever since updating. Randomly the game will drop from 60fps to a total game freeze from upwards of 10-30 seconds from what I've observed. After the game freezes it usually runs around an estimated 1-2fps for around another 30 seconds to 1 minute. Then after that it runs back to normal, before again later it does the same thing.

It gets really disruptive in the middle of games on servers and normal survival.
