The Android and iOS versions work fine! THANKS!
However the UWP version, as started from latest Visual Studio 2017 (15.5) running on Windows 10 Pro, 64-bit, Creator's Version,has the appearance (almost) of being hung. The preview pane is seen on the UWP Print Dialog, but the busy indicator within in runs "forever" and no text appears.
I see that, nonetheless, if I click that Dialog's Print button, printing does occur. However I would never want to publish an app that had such a unusual behavior. Has the sample always been this way? On the other hand, if it used to behave properly, do you have an update to deal with whatever has happened since you first made it available?
