Samsung Health Fitness/Activity/Steps Tracking Broken (Again)

Cronometer is not syncing my Samsung Health activity information at all anymore. No steps or calories burned, nothing - just sleep and heart rate (and as a separate issue why is sleep tracked on the day you wake up and not the day you go to bed? Is there a way to fix this? I've been tracking the latter way for a year now and the Samsung integration is messing up my data). I'm on the latest stable build, though the latest beta build also does not import any Samsung Health activity data.
