Nope, the sample screenshot I posted was with a DRMed book, so no issue copying text within a DRMed book. There might be a flag the publisher can turn on or off though. I still believe the OP's issue is due to the laws in his area as stated by the CS rep. Even if Germany has no such laws in effect, that doesn't mean Amazon is correctly interpreting them. And just perhaps the German language app is used in other countries nearby that do have legal restrictions that Amazon interprets as reason to disable the feature therein. Or maybe the German language app developers just screwed up and accidentally disabled the feature.
