How to close Frozen software update window for iPadOS 15.4.1
I can’t close the software update window that appeared after I installed iPadOS 15.4.1 and my IPad is frozen. It won’t close when I press ‘ok’ and I can’t shut the iPad down either, because it won’t recognise any button touch while the software update window is still on the screen.
iPhone 5, iOS 9
