As a veteran google policy violator I have many stories of anger and frustration I could regale you with, however the only really useful information is that you should just submit a new APK. 90% of the time, it works every-time. The appeals process is fundamentally broken, it is not just you. It takes forever, no-one actually reads the emails, even when you have an account manager that can prod from higher up, it will still take an age only rarely actually getting the sensible response. It is always easier and quicker to just rebuild and resub.
