Since the transition at the end of June 2017, my previously displayed chat contacts in the desktop Gmail interface have not appeared. Now, I am presented with a large empty space that the contacts list used to occupy that invites me to make a call:
I can utilize https://hangouts.google.com/ and Hangouts on my mobile device works as expected. However, I utilize the desktop client for a majority of the day.
Is there a way I can restore my chat contacts to this side bar in Gmail on my desktop?
