Find the contact you want to save an address for (click the hyperlink to see a variety of ways to do this)
You arrive on their profile
Click the Edit Bio button
You arrive on the Edit Bio page
Look for the Address field in the form that is shown on their Bio
If the form on their Bio does not already contain the Address field, there are two options:
Option 1: If there are other Forms saved to the contact’s Bio:
Select one of those other forms (e.g. the New Client form - in the example below)
Let it load
See if the Address field is on that form
If it is, populate it
If it is not, select another of those forms
Option 2: If there are no Forms saved to the contact’s Bio (or if none of the existing Forms from Option 1 contain the Address field), you can add another Contact Form to the contact:
Press the Add another Contact Form button
Select a new Contact Form
Press save
That form is now saved to the contact
Select that form
It loads
Now you can populate the Address field
Scroll to the bottom of the page and press Save
