Yesterday, we pushed out a new update on Android that solved the key overcharge problem. We released the same update for iOS today (we had to pass Apple testing first.)
Make sure you update to build 1.4.1 to avoid getting double charged for keys. Once again, we are very sorry for this problem! We are continuing to monitor our support channels and social media closely to make sure that the problem really has been solved.
Later, we will do an internal post-mortem on what went wrong, recap what happened to you, and apologize again. We feel really bad about this and we thank you for your patience as we worked on solving the problem.
Oliver, Pixelberry's CEO
