I have a multisite install, I updated the mailchimp sync plugin to the latest version and I get a message:
“Mailchimp API has been updated. These change affects to groups references. Please, click here to set the groups again. “
but when I go to set the group / mailing list, I can only see 10 of may mailing lists (I have about 15-20 in total), so I can’t choose the one I want to sync since it’s not in the list.
Note: please refer to this previous ticket, it could be relevant in finding the fix:
