Great but one glitch – Preposition Remix Review

This app is great for teaching spatial concepts (aka prepositions). I love that it keeps data for me. However, when I try to email to myself, the email won't go away after sending or after pressing cancel. Yesterday I thought it didn't send and I sent it to myself 10 times. And since it won't go away, I can't use the app for my next student.
