I just upgraded to MacOS Ventura 13.0. After upgrade completed, Norton 360 setup indicates that I need to Enable Full Disk Access to the Norton System Extension to complete the setup. When checking Full Disk Access status for that extension, it already shows that Full Disk Access is enabled (from already having installed the product). I've tried toggling the extension off/on to see if that triggers the setup completion, but no luck.
The link to the help article did not resolve my issue. Norton System Extension already has full disk access when I check in Settings, but I continually get prompted to change the access.
