Multisite Privacy & Wordpress iPhone (iOS) App

Hi ... I was testing my multisite and writing new content using the Wordpress iPhone (iOS) App. I found that I was getting errors using when using the Multisite Privacy Plugin.

I tried again both without the plugin (and another privacy plugin Private Buddypress) and it worked.

Is there a workaround for Multisite Privacy to be able to work with the Wordpress iOS App or could this be unique to my site?
