Using Ultimate FB to autopost to FB, but cannot boost the posts

Hi guys, i have set up Ultimate Facebook to post to FB, however it appears that I am not able to boost these posts as FB reports the following message:

"Ads creative post was created by an app that is in development mode
Ads creative post was created by an app that is in development mode. It must be in public to create this ad."

I have checked my Ultimate FB settings, and also checked that the following is set to Public "FB > Settings > App"

I've also applied the latest updates since I first discovered this issue and the updates didn't make any improvements.

There are a number of reasons why I would like this to work, namely the integration with FB comments plugin.

The other issue that I have witnessed is that the organic reach is only displaying to myself and suspect that this is due to bugs in the plugin and clashes with FB's "edge ranking algorithms.

Any help that can be given would be greatly appreciated

Thanks
