Charge 3 won’t track CrossFit workouts

[SunsetRunner]

Charge 3 continuously fails to track workout. I have an iPhone. My Fitbit tracks steps, sleep but not my workouts. Heart rate and calories burned are important to me. I have followed and repeated all the reset, reboot, remove and reinstall instructions. I’m sooooo frustrated I’m about to leave Fitbit and purchase a Garmin . Any suggestions before I leave the community?

Welcome to the Fitbit Community, @SunsetRunner.

Thanks for the details shared in your post and for already trying to resolve the issue. I understand how frustrating this is for you and recommend making sure your tracker is syncing. Please note that SmartTrack recognizes activities based on the continuous movement of your arms. Sometimes, motions such as placing your arms on the bar of a treadmill, or pushing a stroller while you walk, may interrupt SmartTrack. Additionally, stopping in the middle of an exercise may interrupt the activity tracking. You can confirm which activities your Fitbit device can track automatically at Which activities does my Fitbit device track automatically?

By default, SmartTrack recognizes an exercise that lasts at least 15 minutes. If your workout isn't being recognized, lowering the time auto-exercise recognition setting to 10 minutes may help ensure it records properly. For more details, see Can I change how my activities are tracked?

Another option to track your CrossFit workout is to start and stop a workout on your Charge 3 using the Exercise app. For more information, see How do I track my workouts with my Fitbit device?

By the way, I've moved your post to Other Charge Trackers board so we can keep our forums organized.

Hope this helps!
