The Filter in Achiiva is used so that you can view information shared with specific Clients or Coaches or things that are Private.
In general this is how the filter works;
If you select Goals, Wheels, Journals or insights from the bottom menu you will see a filter at the top of the screen
From the filter you can choose a specific Coach or Client.
Once chosen the Goals, Wheels or Journals that appear will relate to that user.
Note that when a filter is active it filters all sections. For example if you have filtered your Wheels sections to a particular Client or Coach, when you click on the Goals section that too will be filtered for that Coach or Client.
