Start and End date editing on my Ipad

edited 12/09/19 in Smartsheet Basics

I’m new to Smartsheet. I’m using an iPad Air to schedule construction projects for my company. In the Gantt view when I attempt to edit Start and End dates, the windows for them appear gray and it will not allow me to edit them. The other editing options windows are white and they allow editing. I am an admin in our system. Does anyone have information on how to edit Start and End dates on my IPad?
