People were writing to UWP. There were hundreds of UWP apps that got cancelled and abandoned when Microsoft ditched their Windows Phone once Nadella got in. He kill Windows Phone, he killed native Edge (Chakra JS) and a lot of other stuff to focus fully on Cloud and then AI.

Before that ex-Microsoft guy was responsible for killing Nokia OS/Meego too in favor of Windows Phone - which got abandoned. What a train-wreck of errors leading to the mobile phone duopoly today.
