Annoying crashes! – 69 Positions - Sex Positions Review

I watch ads to reveal more positions and without fail, after a time (maybe between 5 and 10 ads), the app will crash. WORSE, ALL OF THE UNLOCKED POSITIONS ARE GONE when I restart the app. The app should save my unlocked positions after every ad view. Well, it really shouldn't crash, but at least if it does, don't punish me. I tried restoring purchases hoping that might work, but it doesn't. This has happened 3-4 times now, so I'm not sure I want to bother using the app until it's been fixed.
