I converted a map from my Xbox one edition Minecraft to the new Minecraft and then converted it into a realm. Since it was created into a realm, a large number of my friends are not able to eat. It could just be a coincidence but it seems to only happen to the accounts that first played the world before it was converted to the new Minecraft. When they have food in their hands the “eat” does not appear on the screen and pressing the appropriate button to eat does not work.
