Im using 4.13 and this problem still persist.
Is there a bug to the new “Remove From Parent”? It adds “Widget to Viewport” and works 100 percent. However “Remove From Parent” worked only on rare occasions and then it doesn’t work anymore. “Remove All Widgets” which worked 100 percent and its awesome, however more often than not, we do not want to remove all Widget.
I tried adding it in other blueprints or in the widget blueprint itself, both couldn’t remove the widget from viewport. Is there a set up that we should be notified of?
