Doesn't seem to be working in WP Multisite. Help?

The plugin doesn’t appear to be working in WP Multisite. Help?

I saw a previous post at https://wordpress.org/support/topic/multiple-sites-suppor? but .. that didn’t seem to resolve the issue.

Just not seeing the necessary options when I view any pages or posts.

I’d appreciate knowing if this should work in WP Multisite or not.

Thanks,
Gary
