Thanks mate, @uniquelylost,

For “If you don’t do it then each blog should be updated when the admin for that blog logs in to the administration for that blog.”, will the update triggered automatically when the subsite admin logged in? or the admin have to press anything to trigger the update?

Thanks mate,

I did read this before but still dun really grab the idea of it.

Even if I don’t “upgrade network”, all sub-sites show they are using “WordPress 4.9.7” in the source code and backend CMS after login.

Then I wonder if there still a need to do the “upgrade network” thing.
Any idea? Thanks for helping.

Regards,
J.
