Vehicle Setup > PID Tuning - Android seems to have limited functionality?

I am new to PX4 - I am in the process of tuning my drone. I have a H16 Pro rc controller which has Android on it. However, when I attach the unit to my PC I get a whole bunch of additional options that are not present on the Android. One of interest is Autotune - on the PC it is present but on Android this is absent.

Can someone explain this?
