Hi @Bob_Brinza & @klokan054,
I have been discussing this issue with QA and we have been unable to consistently reproduce this behavior in the lab.
This issue seems to be at random from what you describe, and it might even be related to the iOS system itself performing this black bar, I have seen some reports of this behavior on other apps as well, see:
We are of course, still looking into this issue and hope to have improvements in this area, but if you are able to provide any set of steps that consistently get the iPad into this state, please do let us know.
