Until yesterday, Publicize shared fine and the post was public on my google+ page. After a connection glitch when I had to reconnect Publicize to Google+, the auto-shared post was private again on the page and as you said above, I also wasted one hour to look for the privacy setting so that my auto-shared posts are shared public and not just for me. The privacy setting for the apps has disappeared.
Looking forward for a fix to this! Great feature and plugin!
Thanks,
