Specific case: Firmware r109
If your problem persists, please check the firmware version of your scale.
To do that, remove one battery and re-install it.
During the reboot process, the firmware version of the scale is displayed (r1xx).
If the firmware version is r109, make sure the scale is well connected to your WiFi network (WiFi icon displayed on the scale) and wait until the following day.
During the night, an update will be automatically downloaded and installed in the scale. A bug of synchronization (when more than one user is registered in the scale) has been fixed in following firmware version (since r110).
