From the appstore I downloaded a userform-widget. There is no signout-button included. When adding this button on the form it does not show when you are logged in. Ideas anybody how to fix this?
Did you check whether the SignOut button is there in the DOMtree of the HTML document? It is probably there but CSS rules of other parts of the page are probably mistakenly overruling the visibility of it.
If so; add an extra CSS rule for the visibility of the SignOut button.
