Sense 2 ECG reports won't start on Fitbit app

[GGG63]

My ecg app simply doesn't work anymore. It opens, but the analysis doesn't start. It was working till some days ago. No update seems to be available. I switched off and on both my watch and my phone, with no results

Welcome to the forums, @GGG63.

Thanks for bringing this to my attention, and sharing the steps that you've tried. Given this situation, let's try the following steps to see how the Fitbit app responds afterward:

1. Log out from your account and force quit the Fitbit app
2. Uninstall and reinstall the Fitbit app
3. Open the Fitbit app and log into your account
4. Try taking an ECG reading from your Sense 2 and then check your results on the Fitbit app.

In case you need step-by-step instructions on how to use this function, I'd suggest this help article.
