Charge 3 stopped tracking swimming exercises

[Julieavin]

My fitbit no longer picks up swimming automatically nor prompts inactivity.

I have tried restarting but to no avail. Has anybody any advice please?

Hi @Julieavin, welcome to our Fitbit Community! I'd like to follow up and help you with your Charge 3 since it stopped tracking your swimming exercise automatically. By the way, thank you for trying to get this issue resolved before contacting our forums.

I'd like you to try a long restart. To do so on your device, follow the steps below:

1. Connect the device to the charging cable. 
2. While the device is plugged into the charging cable, press and hold the button down for 15 seconds. 
3. The device turns on and shows a battery icon. Two vibrations occur: first a short vibration, then a medium vibration. 
4. The device turns off.
5. The device turns on and shows a progress bar and short vibrations occur. The progress bar completes. Note: A total of 7 short vibrations occur. 
6. Remove the device from the charging cable. The device shuts down.
7. Important: Plug the device into the charging cable again.

After this, check out this help page, which explains how your Fitbit device tracks your swimming exercises.

Keep me posted on the outcome.
