Cant place blocks and water, I can eat even though I am full.

Me and my friend joined my realm since we stopped playing for like 5 hours then got back, but we can't place block. I can eat even though I am full. I can't place black nor torches. Even my friend who is playing on nintendo switch (I play on mobile). As we tested what we can do and cannot do we realize it's a bug since we reset our realm. The things we can do: hit each other, put armors, but we have no idea if we can use furnace since we can't place one.
