UPDATE: 9/26/2018 at 1:21PM - New version of iOS app is in the app store now that adds the iOS 12 support and a slew of other new features!
------------ FIXED! ------------
If you have upgraded to iOS 12 you have probably discovered the the WBTVD Screeners App doesn't work so well. The display of the content galleries and even playback is all messed up.
We are working on a fix and hope to have one shortly but thanks for your patience. See what you get for being an early adopter!
