Why doesn't the updated_at attribute return my last update to a Sell user profile?

Question

When I retrieve user data from the Sell application programming interface (API), the updated_at value doesn't match my last update to that user profile. What causes this?

Answer

The updated_at attribute shows the date of the last update to the user profile.

Updates by an admin from the profile pages below don't change that attribute:

In Sell > Settings ( ) > Manage > Users > Click the agent name to open and edit the agent's profile
