I am trying to download the iOS 13.3 software update to my iPhone 7, and when I click on "Download and Install" in my Software Update screen, it keeps giving me an error message saying "Software Update Failed: An error occurred download iOS 13.3".

Any thoughts?

For the past week there have been a lot of reports of this problem; most likely it is on Apple’s side. I suggest using the Contact Support link at the top of this page or this link—>https://getsupport.apple.com
