Body Battery function not Woking correctly on App

A couple of weeks ago the body battery function started acting strangely on the app on my iPad.  When I click on it from my Home Screen or from health stats, the graph shows in landscape format but the app crashes in that I can’t get back to the previous screen, I have no navigation buttons.  

I have to close the app and reopen it to get back to the Home Screen or anywhere else in the app.  

The body battery function works fine on my android phone, it is only on my iPad I have the problem.

i thought it was a bug in the app and it would be fixed but after a few weeks it persists.

When I click on Body Battery the ‘normal’ screen flickers in for maybe half a second.  It is such a short period I can’t even get screen shot of it.  Then I get the following.


Then there is no way of getting back to the rest of the app.  I’ve tried pressing the buttons in the bottom right of the screen, while they function they do not get me back to normality.  At this stage I have to close the app and open it again.

Any help would be appreciated.

Thanks
