When you initially connect devices such as FitBit, MyFitnessPal and Nokia/Withings to your Heads Up Health account you are prompted with a screen asking you to share certain types of information.
For example, the screen below is shown as part of the connection process for FitBit:
If you chose not to share 'profile' information then we are unable to accurately determine your time zone. As a result, sleep data and other time stamps may appear inaccurate.
With Nokia/Withings this issue will limit our ability to calculate BMI as we need your 'height' data as part of the process.
To address this issue, please disconnect the device/app from your Heads Up Health profile. Then reconnect the device/app and ensure the profile information is shared.
If you have followed the above process and you are still experiencing issues, please let us know and we will investigate further.
