love my surfacepro 4, and really love the drawboard app. Been working great for months. All of a sudden, while the red markups look great in drawboard, when I open them in acrobat, they are all faint and washed out. Verified the opacity, the line thickness, nothing seems to work. Changed the color, same problem. Uninstalled, this time it wanted me to pay for the app so I took the trial (guess that's another problem), but same problem. And unfortunately, their website leaves a lot to be desired with respect to technical support. Posted it on their blog, but if anyone has any insights,truly appreciate some help.
