Sleep tracking

[Members_cNkWN2s]

Galaxy watch 4 suddenly not recording my sleep. Ι have my watch for several months and the sleep tracking was working ok. But about a week now has stopped. Recently there was an update for several apps including samsung health.

Worth while turning it off and back on (fully powered down) it happens on updates some times and requires a re sync.

I have had the same problem since August 13, I have tried everything including factory reset.
