We don't know if or when Tapas would have said something (four days isn't a very long time, it's a small company), and we have only to take or not take that they couldn't at face value. All in all this is just way less disconcerting than the ramifications of Apple and Google auditing the app and the butterfly effect that may result in for creators.
So yes, I'm more worried about what will actually happen to my comic than that Tapas didn't immediately notify us. I'm willing to give them the benefit of the doubt at the time being.
