Glances allow you to see your key account metrics and the FYI badge showing you how many notifications you've received.
You can receive your IB FYI notifications right on your watch similar to the way you receive your text messages, but first you need to have them enabled on your iPhone.
Press the button on the side of your Apple Watch to view the time. Then, swipe upwards to access your Glances. Swipe left through your Glances until the TWS display appears.
If you enabled push notifications, you will now receive IB FYIs as readable messages on your watch in addition to seeing the FYI badge count on the TWS Glance.
