Unlocking dates for smartsheet on ipad & smartphone

edited 12/09/19 in Smartsheet Basics

I am looking for advice on how to enable the dates to be edited on a smartsheet program when accessed on an ipad and smartphone. 

I can edit the dates of the program on a laptop, but when on site, I am unable to change the dates on an ipad or smartphone. Is there a setting I need to change to unlock this restriction?
