Actual behavior

On iOS, only the inner pan is firing (@kmagiera you will know what I mean by this).

hey all! It’s been a while since last activity on this issue. With the new API introduced last year, we no longer expect library users to interface with state change events (the callback is still there but no one really should be using it). Also, in the meantime we’ve changed a number of things under the hood so if anyone here have encountered this problem with a recent version or is willing to help by trying to repro it right now please respond in the comment.
