Can't see sync items when offline
I have four identical "Galaxy Tab7 2" tablets running Plex for Android 18.104.22.1682)
Plex server is 0.9.12.4.1192-9a47d21
On all four I have sync'd various videos. All four list the videos as expected in Settings -> Sync -> Status.
When I turn off Wifi and select the tablet itself in the drop-down box in the upper left near the hamburger menu, all four say something like "open the navigation menu on the left and select a library.
On two of them, there are libraries listed on the navigation menu, and all sync'd videos are accessible in their respective libraries. All fine.
On the other two, there is nothing but "Home" and "Settings" in the navigation menu. But still, navigating to Settings -> Sync -> Status shows all the sync'd videos, sizes, status of "Synced" and the usage bar showing 5GB of PlexSync usage. I can also find the videos with the android app MX Player (granted with nonsensical numerical names).
Also on the latter two, if I go online and connect to the Plex Server, and filter the view of libraries by "Synced", the sync'd videos are shown. (Obvisouly I want them while we're on the road and not connected to PMS, but just as a data point.)
I'm sure I've misconfigured something on the second two tablets, but I can't see what it is.
