Starting a world and spawning is laggy, running around causes frequent lag spikes which make the game unplayable, inventory lag spikes, picking up items causes  lag spikes. Literally everything causes lag spikes. All of these problems came with the latest update. I have a Xiaomi Mi 10T Pro, which is a powerful 2020 phone model with an Adreno 650 GPU, Snapdragon 865 chipset, 8GB RAM, 144Hz screen refresh rate, and 256GB of storage. How does a mobile game like this just perform badly for no apparent reason at all? Even premium phones can't handle this game without lag spikes anymore. Please optimize this game, because this is getting absolutely ridiculous. I hear Mojang employees barely work at all, so I guess that explains the slow and buggy updates.
