Hello, all. I'd like to know if it's possible to "go back in time "before the latest update. I don't like some changes that were made due to the latest one. Is there any way to revert back on an iPad air (several years old now) like I can do on a Windows machine? I know it's possible to reset the unit, but would rather eliminate the update if I can. I'm not as familiar with iOS as I am with Windows.Thank you.
