Fitbit not syncing with app

[SunsetRunner]

I have had my Fitbit for about 2 years. I have no issues with the Fitbit itself but with the app. Since purchasing my new iPhone 11, a couple months ago, the steps I take each day is not recorded on the app. I want to see what steps I did the day or days before. Does this have anything to do with my new iPhone?  Thanking you in advance for any help.

Hi @SunsetRunner, welcome to the Fitbit Community forums. 

Thank you for sharing this information about the trouble you've been having to sync your data. 

Before considering other options, could you please confirm if you already tried all the steps listed here to resolve syncing problems? I was able to confirm that you phone is listed here as a compatible device and you should be able to sync properly. 

In addition, please make sure to keep the Fitbit app updated to the latest version available. 

Keep me posted.

Thank you for replying. I have not tried all the steps. Will do that. How do I keep my app up to date ?  I will do the steps and wait for your answer on keeping my app up to date.

Whenever there's an update available, you can update the app by following these steps:  

ANDROID PHONES

1. Open the Play Store app.
2. Tap the menu icon in the top left.
3. Tap My apps & games. If the Fitbit app has an update, you’ll see it in the Updates list.
4. Tap Update.

IPHONES AND IPADS

1. Open the App Store app.
2. Tap your profile picture in the top right.
3. Scroll down to see if an update is available for the Fitbit app (under Available updates or Upcoming automatic updates). 
4. Tap Update. 

Keep me posted on the outcome.
