You may have noticed that by default we set the children objectives contributing to the parent as 0x. If the weighting stays on 0x, you will see that the child objective has progress but the parent one does not.
To change this so that the child objective contributes to the parent objective, you can follow the steps below.
Click on the parent objective and edit the weighting of the child objective.
Once you've changed the weighting of the child objective, it will start contributing to the parent objective. In the example below, we have the child contributing 1x, which is the same weighting as the key result. You can see the child and parent progress are updated.
