Ace 2 not showing sleep

[BenvenueAve]

My son's Ace2 used to track sleep, but I had so many syncing issues with the app on my iPhone, I thought I just needed to fix it.

I finally got around to:

1. deleting everything

2. reinstalling

3. rebooting the Ace2 per suggestions in this forum

This morning, the Fitbit still didn't show sleep tracking.

Is this like a product defect? Has anyone found a solution to their problem? TIA!

Welcome to the Fitbit Community, @BenvenueAve.

Thanks for the details shared in your post and for already trying to resolve the issue. I understand your concern and recommend changing a clock face:

• With the tracker nearby, from the Fitbit app dashboard, tap the account icon> Ace 2 tile.
• Tap Clock Faces > All Clocks.
• Browse the available clock faces. Tap a clock face to see a detailed view.
• Tap Select to add the clock face to Ace 2. Sync the tracker. 

Our team has started releasing a new version of the Fitbit app (3.41) and I recommend updating the app once you see it available as updates come with new features and bug fixes. You can confirm the steps to update the app in How do I update the Fitbit app?

Hope this helps.

I did happen to change the clock face (which did nothing) but I'm not sure how that's relevant to sleep tracking??
