I have only had my Pebble a week but I love it! I also like the Glance app but don't understand how to use it. I want to use the SmartTime face. I select it by pushing the middle button on the right side of my Pebble. It switches to the SmartTime face but that only seems to be temporary. After a short period of time it reverts to the default home screen. How do I make it stick or become the new default? I have a feeling I am overlooking the obvious.
