In Changepoint 2020, the planned remaining hours are not automatically updated when a project is saved in Project Worksheet (compare What is the difference between Planned Remaining Hours and Remaining Hours?).

Instead, the planned remaining hours are updated automatically during a scheduled job that is run overnight. This change was made to improve the performance of Project Worksheet. 

Users can update the planned remaining hours manually by rolling up the project from the project profile (Actions > Rollup Project).
