Did exactly what the tutorial told me multiple times, hbut mesquito never comes up but "store update bla bla" soon to be followed by "unexpected error".
Edit: Redid the whole process with a fresh amazon.com account, rather than my old amazon.de one and it worked instantaneously.
Probably put a warning somewhere that amazon.com-accounts are required.
