Had users report this as well. The message history segment was present on their phone app, but not on their desktop app, and they didn't get a mobile notification because they were active on their computer at the time. When I had them quit and restart Teams on their computer, the missing messages appeared in the history.
This continues to be on our backlog due to prioritization of other work items. We will update when there is more to share.
