Hi there :)
The card turns halfway, switches sides (correctly) but then instead of continuing to flip left to right, it flips back right to left.
So you end up in the correct state but the animation isn't a full flip.
It's like going halfway to turning the card over and then it magically changing what's on its front face, and then turning back - it breaks the illusion of a "card" existing and isn't the desired behaviour I think.
React Native 0.57
It works fine on iOS though
