I have purchased the Windows App program and I am glad to have done it because of all the hard work that has gone into Paint.net. However, I have a question. I am unable to past any effects into the "C:\Program Files\WindowsApps\dotPDNLLC.paint.net_4.19.6484.0_x64__h55e3w7q8jbva" folder where it resides. I have ownership of the folder and files, I am logged in as administrator, and I have full control. Can you advise?
