With the update 2.0.3 there were issues with the access to iCloud in the apps Wortkraft (not Wortkraft Lite) and Textkraft French. Even tough iCloud was activated on the iPad, our apps claimed that this wasn't the case.
We don't know how that happened, but the access data of our apps might have been deleted, forgotten, mislaid or not accepted by the server of iTunes Connect. Of course all documents are still there.
If you are concerned with this issue, you should quickly load the update to version 2.0.4 and everything works like it should.
We released the update for Wortkraft today, Textkraft French needs a few more days. We apologize for the inconvenience.
