If you hold one finger in place and rotate the other around, it works. It’s a bit more subtle than the default iOS rotate gesture. If both fingers move during the rotation it gets confused with the zoom. I found the best way is to hold my middle finger static and rotate with my thumb. The opposite (holding thumb static) was much harder.
