A. 1. Double-check the settings for the allays in the app. Ensure that the fall damage option is correctly set to 'false'. 2. If the setting appears correct, try toggling it off and then back on to reset it. 3. Test the allays in a controlled environment to see if the issue persists.

B. 1. As a workaround, you can create a command block in Minecraft that negates fall damage for allays. Use the command: '/effect give @e[type=allay] minecraft:levitation 1 255 true'.
