Fitbit Zip is loosing steps!

I am so upset! Recently I have noticed that my Zip is not syncing after a few times tapping, restarting app and sometimes restating IPhone 6. Today it's said I've only been active 9 mins all day with 8,500 steps. I got to sync it and it deleted 2,000 steps back to the last sync this afternoon when I got done walking my dog!

Same thing happened to me in the last few days! Couple of days ago, I lost 2000+ steps and this eveing it went from 11,000 to 7700 steps within 30 minutes!!  I am pissed!! What's going on with the zip?

Welcome to the Fitbit Community @L_Wu @mdiaz24, hope you're doing great today ! Have you made sure that your Fitbit apps are running the latest version (Android, iOS)? Sometimes when running old versions this may cause a mess when syncing your activity. 

Give it a shot and let me know the good news!

I was at work today at a point in my day that I usually have almost 5000 steps and looked down at my Zip and it said time was 12:03 and steps were back to 0.  Later the time had changed to be closer to the then current time.  It counted some steps after that, but when I got home my Zip was saying 0 steps/0 calories and then said 5:09.  Now it has changed to say the current time 5:54 and the steps say 1059 since I sat down at the computer.  I don't have a smart phone.  I only sync at home. What would cause it to reset like that and jump back and forth?
