Fine tuning pitch switch doesn't do anything

When activating fine tuning pitch in djay Pro on an 9.7" iPad Pro, it doesn’t work. Still no fine tuning. See picture below (german UI).

djay pro 1.0.14 Fine Tune is not available. I’m desperately searching for a feature, to tune my song to 440 Hz, see also:
