I have had Bahn.de train ticket purchases fail in the app, but go through on the website. That was with the Chase CSR. Read reports from others reporting the same. Thanks for pointing out that Amex works - instead of going through the interrogation you described, I will just use an Amex card if I run into this issue down the road. Visa and MC really need to make this work seamlessly for their cards.
