Hi! This is a serious statement about malfunctioning. Could you specify what exactly is not working? Cause nothing ever changed to the core logics of the app. And to address an ads 'issue': 1) this is the only way to keep the app alive; 2) it can be permanently removed with a small one-time in-app payment. I appreciate your feedback anyway
