Xenoblade Chronicles 3 has been updated to Ver. 2.1.1. You can see the patch notes for this update below.
Fixed an issue where not having the Expansion Pass would cause the Special Hero BGM, Audio environment in Audio Setting, as well as Notifications to not display.
Fixed an issue with Staying Power’s Art Follow-Up, where activating Fusion Arts would cause the Follow-Up Attack damage to be dealt to the character using Fusion Arts and allies.
