Sense not getting A-Fib notifications

[grillakisses]

I have been diagnosed with A-fib. In 2023, when first diagnosed my Sense gave notifications of my arrhythmia. I have been having the same issue, but am not getting notifications.  It doesn't even show up in the irregular heart rhythm history, even though 2023 is still displayed. What could cause this? How do I fix it?

A warm welcome to the community forums @grillakisses.

Thank you for providing the information regarding the difficulty that you are experiencing with your Sense. 

Please make sure that you have the latest version of the Fitbit app.

Fitbit can only analyze your heart rhythm data for AFib when you’re still. Wear your consumer wrist-worn product often, especially to sleep, and sync your data often to help look for signs of AFib more often. We only send a notification if we see signs of an irregular rhythm in multiple readings, which means you might not receive irregular rhythm notifications if we’re not able to collect enough data each day.

To troubleshoot heart-rate tracking, see What factors can affect my heart-rate reading on my Fitbit device?
