Looking for the feature "knock"

[NunYah]

I have looked for the feature "Knock".  I can not find it in settings.  Can someone please say how to get to this or where.

On the Gizmo - Settings, Accessibility, Knock.

I couldn't find it anywhere in the android app

I as well could not find the knock option. But I do have 2 gadgets with this same issue of not hanging up calls. I cleared the call history and message history and that seemed to resolve the issue for both watches. Maybe try that.

I will try but this has been an issue for a long time. This makes the watch suck and honestly it's an absolute joke. Fix your product. You built it wrong at this point. Admit it and fix it.
