If you can't see all your objectives anymore it could be one of two things:
- They've been marked as Finished by your manager. In order to see these completed objectives, you can click on the Show/hide completed objectives icon and the completed objectives will appear with a grey background.
- Your account is using a setting that only shows objectives that have a due date falling within a certain range. Try selecting a different period from the drop-down menu if you have this option.
