No distances measured with R10

I have exactly the same issue. All data except distances and ball flight.

The last couple of days, the 3 items I display on the Garmin Range, angle of attack, club path, & face to path display a dash on many of my shots. All of the other stats are displayed except for

The past couple of days, I wasn't always getting the club path, AOA, face to path & club face stats while all the other stats were displayed. It seems my ball placement before hitting was not in the right spot (ball to R10 distance set in the app). Once I made sure I was hitting from the right spot every stat was displayed. I don't remember having to be so precise with the ball placement in the past (off by an inch or so was OK).

I may have spoken too soon. I just finished hitting about 30 pitch shots 50-70 yards & most did not display the AOA, club path, club face, or face to path.  All other stats are displayed. 

If you haven‘t read my own reply…

Deleting and reinstalling the golf-App helped me. Before doing that, the range-screen has been black. 
I had no problems since then. 

I deleted Golf App with v2.10 and re-installed it with v2.9. It works again.
