Flashing desktop icon for ALL notifications.
The entire Microsoft Teams developers should use Slack for at least a month. Then go back to using Teams to find out what is missing.
Teams sucks at giving notifications. Desktop icon does not flash when receiving a message on teams channels.
The "Last read" line is also horrible. I have to scroll back up and then down to find out what has been written since I last read something.
And there is no chance I'm gonna activate email notifications for a simple message.
The other alternative is for Microsoft to buy Slack and bundle it with other Office products rather than Teams.
