Multisite disconnected from core

I just updated my multisite network to 6.3.1.

I had trouble updating before where there was an error (turned out to be a permission error), so I had used the plugin “Fix Another Update In Progress” to unlock the “Another update is currently in progress” message I kept getting. I am the only admin/user, so I unlocked it since there was no reason to keep it locked for possible ‘conflicts,’ so i thought.

I did succeed in upgrading, but for some reason, out of my 7 multisites, 3 did not update – they seem to be “stuck in the past”, or “disconnected” for a lack of a description, on the dashboard it still says the 3 sites are on version 6.3.

I’m still getting:
“WordPress 6.3.1 is now available!” and
“Thank you for Updating! Please visit the Upgrade Network page to update all your sites.”
– messages on these three sites, and plugins that I’ve since installed after updating do not appear in the plugins list despite network activating them. Additionally, despite deleting one plugin, I can still activate it and see its admin panel from these sites, but not the “normal” sites. The other multisites are able to see the new plugins, but not these affected 3 sites.

There doesn’t seem to be a pattern to it as far as I can see, two are ones I use often but the other one I have not touched in 5 years.

I have done a database backup restore from pre-update several days ago, but that did nothing, issue still remains.

Attempting to reinstall 6.3.1 or upgrading the network does nothing.
