Today my SpO2 clock face has lost the color in the bands. So for example the step counting face shows a grey arc, with a small amount of blue at the left hand start of the arc. During the day the steps showed up as a green dot on the arc until it worked away around to the end when it disappeared. The same thing happens for the other faces. I've tried un-installing and re-installing, but that doesn't work, maybe because it won't un-install.
Any suggestions?
