How do I sort by what is due next?

You can sort your view of People, Companies, Projects, and Deals to see what is due next. People, Companies, Projects, and Deals are displayed first by To Dos and Next Steps, and then Keep in Touch Reminders are displayed next. So you'll see what is due first and then Keep in Touch Reminders will be shown next as you scroll down further. 

1.) Navigate to the People section.

2.) Tap on the Audience menu and 3.) Select your Audience. 

4.) Tap on the funnel icon. 

5.) Tap on the Sort By menu.

6.) Scroll down the menu and select Due Next.
