Steps have not refreshed overnight, and no sleep tracked

Saw another question raised last year on this forum but with no resolution. 

I noticed this morning that my steps hadn’t refreshed overnight. And that my sleep wasn’t recorded. I’d had the watch on charge just before going to bed. 

I’ve tried restarting the watch, and disconnecting and reconnecting to the Garmin app, but issue still prevails.

What’s the resolution for this please as I rely on my step counts that sync with other apps.
