Teams occasionally "going offline?"
I keep Microsoft Teams open at all times. Sometimes when I have Teams minimized, I will show as offline to my coworkers. I won't receive any notifications of messages from any Teams and/or Chats, even if I am @'d. If I open the Teams window from my task-bar, it will show the offline symbol for everyone briefly, before eventually showing everyone's status correctly (and mine to everyone else). My Teams notification settings are setup as attached:
