Charge 5 ECG app, receiving an error message

[Rg2364]

Have had the Charge 5 for almost two months and the ECG app has been working since the first use of the device

. Recently I have been receiving an error message that states “Please reopen app”.  How do I go about this?

Welcome to the Fitbit Community forums, @Rg2364. 

Thanks for the information that you've shared about this inconvenience with your Charge 5. 

While this is odd, may I know if the Fitbit app is updated? Is your Charge 5 syncing correctly? Have you also completed the Heart Rhythm Assessment on the Fitbit app?

In the meantime, please give a try to the following steps:

1. Uninstall the ECG app from your Charge 5.
2. Force quit the Fitbit app and restart your tracker.
3. Open the Fitbit app and pull down on the screen to force a manual sync.
4. Install the ECG app one more time and make sure the permissions are enabled.
5. Tap Discover > Assessments & Reports > Heart Rhythm Assessment to double check if still appears completed 
6. Try taking a reading one more time and let me know how it goes.
