On iOS9 when clicks are turned on, I hear the keyboard when I type in textarea, and I get a options selector that makes a clicking sound when I cycle throught it. And they all go away when I turn it off.
However, on iOS10 when have clicks turned on, I hear the keyboard clicks in textarea, but the options are not a cycler like in iOS9 they are a menu that you select from (and browse through). I can't reproduce it. Got a web site that shows you the cycler that clicks?
