Soda DJ app Pitch fader issue

I have an issue with the pitch fader. When I try to adjust the value with my finger it stays in the middle, no matter it’s the 1% , 5% or 95% type, same issue on all of them. I can see the slider flickering up and down a bit but stays in the middle and the BPM of the song stays also the same. When I double press on the slider I can see that the minimum and maximum value is only 0.1 or -0.1.
I have iPad Air 4 with iPad OS 15.1 installed on it.
Anyone experienced the same? Any suggestion how to fix it? Please fix this via a future update.
