💡 Always ensure your game is updated before entering the Union Room, as players on different versions (e.g., 1.2.0 vs 1.3.0) cannot interact or trade with one another. To help you get the most out of this update, let me know: Are you trying to shiny hunt Arceus or Darkrai? Do you need help completing the National Pokédex ? Are you having trouble triggering the Azure Flute event ?
