You can edit your lease details by going to the top right hand menu on your Flow app and from the next screen choose My Lease.
Change the details you want on the next screen. Select the field and enter the new details.
When you're done with the update select Save Details.
The lease amount you select will be displayed on the rent tracker when you track your rent. You are able to edit this amount directly from the rent tracker feature.
Update your lease whenever details change and, of course, when you move.
