Doesn’t save, always crashes – Lake: Coloring Book for Adults Review

My app keeps crashing any time I open it. It has said I have my second free “one a day” painting ready but never lets me open it. It also didn’t save my last three paintings or allow me to stop a painting and come back to it. I emailed the developers from their website but have not heard back yet about an update to fix these issues.
