RESOLVED - Delay in Sync, Overall Sluggishness, and Fitbit/Partner Sync Issues

Updated: Wednesday, February 10th, 2021, 10:01am PDT

Current Status: Resolved

Fitbit has resumed syncing as normal for members as of 2.8.21.  We have been closely monitoring the Fitbit integration and our Fitbit sync backlog the last two days to ensure stability and consistency of sync through peak sync periods prior to marking this as resolved, and have seen sync has been functioning as expected with no issue.  

Please note: if you are having trouble with Fitbit data sync, you may be experiencing a glitch, or a something other than the issue causing the symptoms mentioned in this article.  If you are still having any trouble, please follow the triage steps outlined in this FAQ.

We continue to apologize for the frustration of these ongoing issues.  We know it's been an extended amount of time with our members having to deal with these symptoms, and understand the frustration this causes.  

We are making larger scale plans to investigate and address the root of what is causing these systems to not operate as they should.  This will be a long-term investigation that will continue throughout 2021.  In the mean time, our team has implemented monitoring to try to identify when issues are arising asap, in order to minimize and address any re-ocurring symptoms if/when they arise through the year.  

Additional Messaging:

Starting around 5pm on Wednesday, 1/13, our team noticed a few of our services in a degraded state. We had been making changes to address these services to get them healthy again, but over the course of the first week we were still seeing intermittent spikes, causing sluggishness and trouble with data syncing in the program.  

Symptoms related to that issue included, but was not limited to, the following:

• delays in sync (both in data logged between web and apps, and in profile/setting changes to the rest of the program)
• general sluggishness across the website and apps
• steps from partners delayed or not syncing
• Fitbit data not syncing or syncing slowly
• Issues logging to diary (barcode scanning, recipe creation, etc)
• Network/Sync/Server Errors in app

We were able to get the majority of the above symptoms to subside the following week, though from the 13th through today, MyFitnessPal members linked to Fitbit experienced a daily delay or stoppage in Fitbit sync.  The stoppage occurred during the day, and  Fitbit sync backlog will caught up in the evening, providing data sync later each day.  No member went more than 24 hours without Fitbit data sync due to this incident. 

We do apologies for the continued issues. We have been working hard to get the program functioning as normal, and are working on a longer term plan to try and minimize long term Fitbit sync issues like this in the future. 

Thank you for your patience,
MyFitnessPal Staff
