This bug does not apply in worlds, just in the Bedrock dedicated server.

I noticed that when attempting to eat berries, the animation plays, but no berries are depleted from your hotbar and no hunger is restored.

This bug isn't really high priority, just wanted to point it out. I usually take berries with me on long journeys as it is an easily-acquirable food source and if I need more I can grow it without needing water, a hoe, etc, so not having them as a food source anymore is slightly disappointing.

Edit: This glitch happens to all foods from time to time, restarting the client fixes it
