V51: Cannot connect to Roland Cloud via Wi-Fi.

As of November 2025, we have found following issue when installing Instrument Expansions and Kit Packs to the V51 via Roland Cloud Connect, and we are working on a software fix.

• Roland Cloud Connect App
  The following error message appears: “The connected device is busy. Please try again later.”
• V51 Drum Sound Module
  Wi-Fi status does not change from “Connecting…” to “Connected.”
