Using CMC with Community Builder in Joomla 3.7.5... a new user signs up and is added to both Community Builder and the MailChimp list. All synced data is stored. Great! However, how does someone edit the data? If a user edits their CB profile, does it edit those synced fields in MailChimp?

For a site admin, where would they edit the user data? There's no way to do it through CB as the synced data doesn't show there. When I go to the CMC component and Users to edit there, I can't save any edits because the users are created without any LIST assignment. The list is missing... plus I can't even select one. So something is messed up although it is working at least half way.

Maybe related, but when I select my list in the list management and start the sync process... nothing ever happens. The sync button gets disabled so I can't click it again... and I wait... and wait... but nothing ever happens. The list has about 22k users on it.

Any help is much appreciated!
