I tried reporting content labelled as "nazi flag" in an iOS app to no avail. I submitted multiple tickets in different places, sent multiple emails to Apple and to the application developer.
Yet nazi flags are still present on the home page of Divoom application. Also present in this ages 4+ rated application are plenty of drug symbols and other assorted strangeness.
I spent way too much time with this and am amazed just how non-responsive Apple has been.
