I have a couple of slide decks that I publish to the world. Oftentimes, they include hidden slides. When a published deck is opened by someone using an Android device who has no privileges to the deck, the deck is opened in a browser and hidden slides are not shown -- an expected behavior. 

However, if that person has the Show app installed on his device, the deck is opened in the app. In the app, the hidden decks are shown, albeit with a red-eye-with-a-slash icon on the lower right corner in its thumbnail. I verified this once again on someone else's Android phone, first uninstall the app entirely and then re-installing it.

I would think this is a grave bug. I am horrified to realize this just now. I have published some of my decks for a year or more, without realizing people could see hidden slides.

Woud you please fix this ASAP?

Thank you!
