The DAAD has sent me a swift reply. Here is my translation:

Dear Mr. [my name]
Unfortunately the person responsible for the DAAD web portal is on vacation
leave. However, I can assure you that we are always eager to provide forms
for all web browsers and operating systems. Why it didn't work out well in
your case I can't tell because I lack the expertise in this issue.
Additionally, we have begun to work for a replacement of the PDF form
technology used so far, so that, hopefully, you will encounter less technical
trouble with your next application.
I wish you the best for your applications.
Best regards
