When a conversation is reassigned to a teammate, it doesn't move to the top of the Inbox — sorting only reacts to new incoming messages, not assignment changes. This makes reassigned conversations easy to miss, especially in high-volume teams, and leads to manual pinging outside the platform to flag the handoff.

When a conversation is assigned/reassigned to a user, surface it at (or near) the top of that user's Inbox view, independent of message recency — similar to how an unread/new-message conversation is prioritized.
