The % Completed metric is removed from the Project Dashboard:
You can still see the Completed Billable Hours / Completed Hours on the Project Dashboard:
Why do we do this?
% Completed refers to the percentage of billable hours / total hours occurring before today. It does not refer to how many tasks in the project have been completed.
Upon receiving feedback that the metric is confused with the project completion status, it is removed to avoid misunderstandings.
