When you open up your broker app, tap on the left corner to view the menu. From here, if you see your picture and name, you are branded to yourself!
If not, you'll see this:
Tap on "Agent Search" and start typing in your name to find yourself. Once you've found yourself, tap on your name.
From this page, you'll tap on "Set as Preferred Agent".
You will now see yourself in the menu of your app and you are officially branded to yourself.
Once you've branded, whenever you tap on "Share This App" you're sharing your branded app, and anyone that downloads from the custom link created will be automatically branded to you.
