First, update your contact information in your Member Hub.
NOTE: if you add new info, the system will automatically default to this new information. If you do not want this to be your primary/default email or phone, edit the email/number you want to be default and check the default box. Don't forget to hit Done instead of cancel.
Within fifteen minutes, your contact info will be updated on your user record in Matrix.
To update your user record on your listings, you'll need to update your information on each listing. This can be updated by pressing refresh on the agent information in the input form as seen below. If it does not update, you may have to wait a couple of hours to try again after the system updates.
