For some reason in my 5.1 project adding a widget to the screen does not show the widget. It worked in 5.0 exactly as it’s set up. It works in a new project too so I don’t understand what is different.

I’ve tracked down the problem for myself and I assume it’s the same for you guys. My GameInstance class in CPP had overridden the Init and OnStart functions, and hadn’t called Super::Init(), etc. Make sure you’re calling the parent inits!
