iPad reset
Hi everyone, so I bought my son an iPad 7 for school but now the school has decided not to use iPads anymore as they can't afford the apps. They set up the iPad with the schools account and it doesn't have a password. I want to reset the iPad to factory settings but when I go to settings - general - reset the option to erase all content and settings is not there. So I am unable to reset the iPad to use for my own use at home. It won't even open up the app store for me. Even the section in settings to sign iPad into iCloud, App Store etc is grayed out.
Is anyone able to give me a step by step instruction on what to do here?
iPad Pro 10.5-inch, Wi-Fi
