Universal App Platform (UAP) is the next big thing from M$ to try and convince people to buy their crummy products
(cue usual Boris anti-m$ rant)
But as when windows 11 comes out it will be known as Joint App Platform, followed by another change to Joint App Version Authoring... or Java for short
And the way they sell the different layouts thing smells distinctly of Java swing too
Hope they've got good lawyers :)
