Summary:
Microsoft 365 Copilot mobile app will get a new chat-first design starting late April 2026, with updates to navigation, chat input, and voice interactions.

[Introduction]
We are introducing a refreshed chat‑first design in the Microsoft 365 Copilot mobile app. This update modernizes the interface and streamlines navigation to make it faster and easier for users to start, continue, and manage chats. The improved experience is based on customer feedback and aligns the mobile app more closely with the broader Copilot visual design. The updated design will release first on iOS, followed shortly by Android.
[When this will happen]
Public Preview: Rolling out in late April 2026 and expected to complete in late June 2026.
General Availability (Worldwide, GCC, GCCH, and DoD): Rolling out in late April 2026 and expected to complete in late August 2026.
