Minecraft Version : 1.16.100.04
Based on Minecraft Changelog (https://feedback.minecraft.net/hc/en-us/articles/360052592091-Minecraft-1-16-100-Bedrock-), the achievement screen has new design UI from the Beta, BUT MY ACHIEVEMENT SCREEN still same like another Version of Minecraft 1.16, I've update my Minecraft to 1.16.100.04 but the Achievement Screen still same.
