ACE is Really slow to sync and doesn’t track sleep properly

My 10 year old uses the ACE 2, and it is REALLY Slow to sync with my iphone (sometimes takes 5-10 minutes).  My own Fitbit flex syncs in less than 10 seconds.  

Also, He goes to bed at 9pm, but it often shows his sleep time as well after mindnight or even 1am, but he’s fast asleep when I check on him every night between 10:30-11pm.  

Yes, the clock is set correctly in our time zone, and he’s not faking being asleep.  I can tell when he is. 

I’m most irritated by and looking for a remedy to the syncing issues.  But the other glitches (screen goes dead occasionally too) are also annoying.  Seems subpar for the Fitbit brand, in my experience.  any ideas?

Also- I have it on All-Day sync, but it doesn’t sync unless I open the app, and “pull down” the screen to force a sync and refresh.  

And, battery level is always over 50 %.  He charges it every day for 20 minutes while he’s in the shower/getting ready for bed.

I also allow background app refresh for the Fitbit app in my iphone’s settings.
