UPDATE: never mind, I think I figured it out: The "Sandmann79" package had 2 addons: 1) Amazon [Discontinued] and 2) Amazon VOD Addon. I guess the 1st one (which was discotninued today) only worked for Amazon.de Prime Video (e.g., German version of Amazon Prime Video).
Anyways, problem solved: just don't install that "German" version of the addon!
