MS Teams:

*Notification*: Bob sent you a message: "Hello King of Lithuania. Got a minute for a call? Andrew told me <...>"

Open up Teams, open chat with Bob. Last message received -- 2 weeks ago. Chat summary on the left (chats list) shows the last message was 2 minutes ago with "Hello King of Lithuania. Got a...."

Prolly just javascript failed to fetch the full message to display it in the chat.. refresh the Teams tab
