I'll give Foxit a go then since we use it at work and get it from the Microsoft Store. Foxit MobilePDF works on WIndows 10 laptop right? Is it better or more secure than the free one from it's website?I am not sure if Adobe Reader DC (it is not the UWP app in AppContainer) can be safer than Foxit Reader. The first has the Attack Surface much bigger even if you use the AppContainer setting for Adobe Reader DC. Did you try Foxit MobilePDF?
