Initially, I started buying the Minecraft Android game in version 1.19. I play as usual and there are no annoying things such as lag, frame drops, and so on. But after updating to the latest version 1.21, I just felt something disturbing. When playing survival, I often experience severe crashes and even frame drops in any condition, So I often died from being killed by mob monsters just because I remained silent when it happened. Sometimes I also fall off a cliff because I can't stop the lag. I say frame drops and lag, because I'm not the only one who experiences this, many people still complain about this. Even though I have lowered the graphic quality of the Minecraft game, but after I tried it, it was still the same and experienced crashes and frame drops. Please help Mojang, I'm very sure you can fix this frame drop. I hope you can increase players' comfort when they play later. Thank you so much
