All Data For The Day Is Missing After Updating The App

I had about 3500 steps yesterday when I noticed I had an update to do. I did the update and got about another 7000 steps that showed fine on my Fitbit. When I synced on the app though only the 3500 steps/active minutes that I took before the update are showing in the app. It's after midnight so I can't even try to re-sync to get all that effort logged. I have restarted my phone. Uninstalled and reinstalled the app. Restarted my Fitbit. I think all that data is gone forever. If so that's so frustrating for my tracking and averages.

Actually, you should sync your device again, and I think if you look back to yesterday, you'll find all your steps from yesterday already recorded.  Just because they didn't show on the app doesn't mean they're lost.  Your Fitbit keeps data for up to a week before automatically erasing it.  Once you sync it again, it will show.
