pdf's that have been set as tabs are not avalable on mobile devices
When I store a pdf in the files section it can be opened on my mobile device. For some reason if the same pdf is made into a tab it is not available on the mobile device. Word and Excel files that are set as tabs work fine.

I would love to see this update. Now, I can open tabbed Office files and Wiki but not PDF.
