Steps not updating to Challenges

[SunsetRunner]

Steps not syncing to challenges. I realise time zones make it different. I don’t use any 3rd party trackers. Just simple walking. 
today I have done 27,000 steps and it’s saying 7,000 in a challenge. It hasn’t updated at all after a 5k walk within the same Timezone.

please help...

Hello @SunsetRunner, welcome to the Community Forums! It's a pleasure to assist you today, sorry for the delayed reply.

Thanks for bringing this to my attention and for all the details that were shared in your post. Below you'll find all possible reasons for this issue: 

1. Your steps have fully synced to our database but you're not viewing the mobile app dashboard in Live Data Mode. (Live data mode would show the word "connected" under your tracker tile). 
2. You manually logged an activity. Steps from manually logged activities do not count toward challenges; only steps recorded by your tracker or MobileTrack are counted toward challenges. 
3. You used MobileRun to track GPS data with your app. Only steps recorded by a tracker or MobileTrack are counted toward challenges. 
4. All challenge participants are not in the same time zone. 

We also recommend waiting 15 minutes after syncing your Fitbit data to see if your challenge updates. For more information, see our information about challenges at: What should I know about Fitbit challenges? 

Don't hesitate to ask me any additional questions you may have, I'll be waiting for your reply.

This is also happening to me. I'm part of two challenges. One shows the correct steps but the other doesn't, it's off by over 14,000 steps. There is a difference in time zone, but it is only 2 hours. I did not have this issue with last week's challenge with the same people.
