We don't get any notification whatsoever for messages in chat. No sound, not even a faint one. No banner. I've tried to remedy the lack of sound but no luck. From the other comments, even if I managed to hear a sound, I might miss it. So far no one in our company uses Teams and this is part of the reason why. We urgently need this. I don't want to have to get Slack in addition to Office 365.
