You should see the update listed under the 'Updates' tab at the top. It should be version 2.50.069. If you do not see the updates tab or if you do not see DeskScapes listed within it, click the orb in the upper left corner of Impulse and then click 'Preferences'. Click the 'Reset Data' button and let it do it's thing. Once you get signed into Impulse again check for the update.
