How do I get rid of a pop up sidebar on in ipad 14.1

Hi there, fnover!

Thanks for reaching out to the Apple Support Communities! That's a great question you have about removing the pop-up sidebar from the iPad screen. It sounds like you're describing the Today View. Please take a look at this article to Add widgets to the iPad Home Screen:

"Open Today View

Swipe right from the left edge of the Home Screen or the Lock Screen."

"Remove Today View from your Home Screen

1. Touch and hold the Home Screen background until the apps jiggle.
2. Turn off Keep On Home Screen, then tap Done.
3. When you swipe left on your Home Screen, Today View will move off the screen."

If this is not the case, feel free to circle back with more information about the pop-up you're seeing.

Take care!
