watchOS 3.1.1 may have fixed one complication for me. Previously, the Activity Analog watch face showed the Heart Analyzer complication in white outline. Other watch faces I tried showed it in red. From the AA watch face, pressing the white heart outline wouldn't open the app an give me any results. It just didn't change at all, didn't do anything at all.
On a couple of other watch faces where the complications showed as a red heart, it worked as it should. Now with 3.1.1 the white heart outline on the AA watch face behaves properly. So, yay!
