App crashes!!! – Sign Language for the Classroom: ASL library Review

I have used the signs from needs outreach in the past when it was avaliable online for free and it was a great help. I was excited to see there was an app. Disappointed that you have to pay for what was once free. But my complaint is the app crashes and closes and yet still shows to be running in the background. Please fix this!!! I am sure this will be a great tool if you can get it to work properly. Thanks.
