Can't update one Windows pc beyond version 22.22.4.11

Yesterday, for the first time in a couple months, I turned on a pc I don't use very often.  It has Windows 7 (with Microsoft Extended Security Updates). I checked Norton and it was at version 22.22.4.11.  My other two computers (one Windows 10 and one Windows 7) are at version 22.22.6.10.  I ran Live Update on the computer with 22.22.4.11, but no change.  Tried several times throughout the day, and re-booted a few times.  Also, New Version Check from the Help panel takes me to a web page that says I have the latest version.

Any idea why this is happening?  Is it possibly a server-side issue, e.g. all Windows users would be unable to manually update version at the moment?  I know that new versions are released in a phased manner, but I didn't think a computer would be purposely kept at a version that's almost four months old?  If this is indeed abnormal, is there any way to address it other than a manual download and install?  I don't mind having that computer remain on 22.22.4.11 for awhile longer, but obviously I don't want that to be permanent.

Thanks.

Today Live Update was finally able to jump me ahead to the newest version, 22.22.7.14.  So it must've been a server-side delay, probably intentional.
