As a Developer, you have the ability to add and view warranty dates of units in Tribe Home.
Here are the following steps on how to do that:
1.) Choose the community you would like to add warranty dates to,
2.) Go to 'People & Units' and then click on 'Units'
3.) Click on the unit you wish to add the warranty date to
4.) Scroll down to the bottom where it says 'Warranty Information'
5.) Click on 'Edit' and fill out the start and end date of your warranty (typically the end date is end date of initial one year warranty). Once you have selected both dates, click the 'Save' button
