Hi,

After a fresh install, I seem unable to create any site in or to move any existing site to any new network created.
I understood you have to create the sites from the principal network, is that right? That works, but I can't transfer them afterwards (I tried both methods: from the network page and from the sites page).
I do manage to create sites from the wp-admin of a network, but they don't seem to work at all if I do that.

Am I doing something wrong? Is this plugin currently working with WP latest version? (5.6)

Thank you very much.
