breath

The breathing app under the previous OS on the Apple Watch would periodically during the day remind you to breath. I thought this was a nice option. However, under OS 8.1, when I go to the mindfulness app and click on breath, then I go to durations and select one minute, then the <Duration at the top of the screen doesn't work. I can't get back to the breathing app. It shows me my selection of times, 1 minute, 2 minutes, etc. but I can't get it to go back to the breathing app to use the breathing app. Does anyone have any suggestions?
