iPad Widget Gone?

The widget feature for the Khan Academy app on my iPad seems to have disappeared. I previously had the widget that listed my favorites on my screen to have quick access to my courses. Several days ago, the widget went blank, no words or information, just a blank box. First I tried just opening the app and then updating the app. Then I deleted the widget, but when I went to re-add it, I found that Khan Academy and its widgets were gone from my available widget list. I’ve tried deleting and reinstalling the app, I’ve tried restarting my iPad, and I’ve made sure both my iPad and the app are up to date. Was this featured removed from the app? Or is this a glitch?
