I have just had my first experience of the new experience for the first time. To say it is a retrograde step is an understatement. There now appears to be no option to remove all assignees from a task without manually removing everybody by deleting them and it doesn't have the option to assign a different number of hours to individuals on the same task, thus creating extra work in having to duplicate for each assignee if you want to give them different number of hours.
This really breaks a huge part of our work and processes.
