No step count on Huawei watch

I made a face and the step value (#ZSC#) stays at 0.
To be sure, I used 4 different faces (not mine) to see if something change, but no way.
I know that the watch is able to count steps, because I see the report in Fit on y watch.
Or is it my smartphone which does the job ?

Any reader with Huawei watch has a step value ?
