Add German Bible (Einheitsübersetzung). Is now in iOS app, so rights shouldn't be a problem.
Roaming between platforms only makes sense if they have the same content. I work with iOS Gospel Library (prepare Sunday School lessons etc.) on the train to and from the office. At home, I would love to find that work synchronized on my PC.
As this is a content issue (We and Android use Content Platform 17, but iOS uses a different source), we can’t do anything to fix this issue. The content team will need to push out an update for CP 17 so that Android and Windows will get the new German Bible.
The new Windows 10 version of the app, currently in development, already uses a newer content source and will release with it when it is ready.
