Hello Pautorgom,
It sounds as though you're attempting to disable Allow Finger to Swipe From Corner in Settings > Gestures on your iPad, but the setting enables automatically. If so, have you restarted your iPad Pro by following the steps listed below? If not, follow these steps then attempt to disable the feature. While restarting is a simple step, it can be very useful in resolving issues.
- "Press and hold either volume button and the top button until the power off slider appears.
- Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restart your device.
- To turn your device back on, press and hold the top button until you see the Apple logo."
Restart your iPad
