GaoFit and Sleep data from the watch

Hi everyone,

I’ve been enjoying my Lemfo LEMP for a few weeks and I do find the GaoFit app kind of good to keep track of the stats gathered by the watch.

Last night, I wanted to try the Sleep monitoring feature and on the watch, it does seem to work but I cannot get the data transferred to the GaoFit watch, like for the pulse and the O2 data.

Is there something I am missing or it just does not work?
