App not showing heart rate graph nor resting heart rate

[I1987]

I have had this strange problem for over a month now, not all days though. But I cannot figure out what is going wrong.

My Fitbit is measuring my heart rate almost all day fine. But the app won't show it in the "heart rate section" (see image 1). It also does not give me a resting heart rate for these days (in the resting heart rater graph). 

And now comes the strange thing, if I click on anyday with a graph, the app allows me to swipe left and right to get to previous day's, and there the heart rate data of these days IS visible (figure 2 and 3)

I worn the tracker all days, all days without a resting heart rate in the graph are "missing"

This week, no graph of Monday or today, only tuesday

Graph of tuesday

Graph of today

What is going wrong here? Both app and tracker are up to date. I reserved the tracker already, signed out and back in from the app and reinstalled the app.

I have never paid for premium so can't save anything. It's a semi effective
piece of gear as long as you don't rely on it.

Fitbit is okay with collecting money but sucks at solving app issues.

Agreed entirely.
