I have a brand new cendence use with a CS for a I2. When I hold the ISO button and roll that doesn't work. Good with aperture and shutter. Did I miss something ? Good also in the app manually.
In settings you will find that you can have 3 custom settings for individual users. There is also a "Reset" toggle in that screen which will bring all things back to the default.
Can you please have a try? Thank you.
