iOS 15.2.1 installation
I can't install iOS15.2.1 into my iPhone12 using iTunes. It comes up immediately with the message ""To update your iPhone to iOS 15.2.1, you need to install the latest version of iTunes". I have gone to Help/Check for Updates and it says I have the latest version, 12.10.11.2. I went to the app store and downloaded and installed a new version anyway, same result.
Is iTunes no longer an acceptable method of updating phones?
iPhone 12 Pro, 15
