To customise your Lumi dashboard for mobile use, you will need to edit your Project Dashboard from your computer.
From your Project Dashboard on your computer, select the settings wheel in the top right hand corner of your dashboard.
Then, select the mobile phone icon to edit mobile dashboard settings.
HIDING / CHOOSING WHAT ITEMS ARE SHOWN
A small eye icon 
will then appear on each board item in your project. This indicates that this item is on the mobile dashboard. To remove it from mobile dashboard, click the eye icon.
A slash on the eye icon 
will then appear, confirming this will not appear on your mobile dashboard. The items you select to view on your smartphone will usually be the most commonly viewed or important items of your Project for easy access.
Alternatively, you can click into each board item individually by selecting the settings wheel 
on the individual dashboard item and customising your preferences in the ‘Mobile Settings’ section. You can click the ‘Show in Mobile View’ button and customise whether this board item is automatically viewed on a smartphone.

Usually 'Push To Top' your most used card category or saved search. Documents, Boards, Kanbans and Lists are designed to be looked at on a computer screen.
