I use Linghtroom CC on my pc computer. The recent updated version of LR has not been working on the gradient feature. Everytime I mask an area with a gradient tool I can not see the editing changes because the red masking doesn't go away. Is there a setting that I may have missed that would make it wor?. The LR on my iPads work just fine but I would like it work on my PC as well. Can anyone help me on this?
