Heart rate graph not showing the line

[DeinGesicht]

Heart rate graph isn't showing the line this morning. I've tried all I can re resetting app etc, still blank. Anyone else?

 I can long press, but it shows only two figures (see example above). Not happy. It's the most important metric I use the device for.

It's working now... 🤷🏼

Hi there @DeinGesicht!

Thank you so much for reporting that yesterday the heart rate graph was not showing the line. Thanks for all your efforts and for sharing that it works now again. 

Have you already updated the latest version of the Fitbit app?
