Great App! Bad Bug! – Marlee Signs Review

I love this app! It shows very useful and practical signs that can get you through a simple conversation. Unfortunately, after a period of about two weeks during which I didn't go on the app, it stopped working! I had bought all of the video lesson packs and suddenly none of the worked. Even after the latest update they're still not working! Please fix it!
