I was measuring drawings on my Adobe and it was working perfectly fine. I managed to do about 3 measurements on one drawing and went to do the fourth. (I have set it up so that when the measurement completes it turns pink to highlight the area). When i went to do the fourth measurement when I connected the last points (Area tool) the line stayed as the default thin red line, showing no indication of size except in the bottom right hand corner. Then I moved on to do the next measurement and the minute I clicked to start the next measurement, the fourth measurement dissapeared completely.
Now I also cant do any other measurements on any other drawings, as the measurement never stays. I am using the desktop app.
I have already tried the good old turn it off and back on again, I have also logged out of my adobe and back in again, i have shut adobe down and reopened it as well.
