We are currently testing the new UI in version 15.3. It seems odd to me that you search and add team members on the conversations tab. But when you want to create a new task and assign someone from the team to the task - the people you have already added to the team are not shown anywhere under the Task/team flyout.
Am I missing something? Or should we expect project managers to search for team members every time they create a new task?
My expectation would be that team members were shown on the flyout and you could simply drag and drop them on the tasks you create.
