Health app stopped working

[mrex]

Health app stopped tracking stepped floors couple days ago. It calculates steps but not floors anymore. The last record is from 29.11.2015.

Tried:
- Restarting the phone
- Toggling on/off switches under the privacy settings (that health app can monitore data provided from sensors...)

6s+/ios9.1
