Flick keyboard doesn’t work on the big iPad Pro 12.9” as it has a full sized keyboard.
If you have a smaller iPad then check that the feature hasn’t been switched off accidentally. To do this go to Settings app > General > Keyboard > Enable Key Flicks
P.S. Unless Apple added flick keyboard to the 12.9” during the beta? Can anyone comfirm?
Anyone has any idea why this is not implemented on iPhones? Flicking for numbers is great on my iPad pro 10.5 and would love to have it on my iPhone 7 as well..
