Built in Track Pad in MacBook Pro is not working

Trackpad in MacBook Pro is not working propperly with OS X Sierra

I am currently using a MacBook Pro 13 Inch (Mid 2014) and I´ve installed the new OS X Sierra on it. Since the installation, the integrated trackpad is not working properly: For instance, two important tools for my daily work:

a) Mission Control: (move fingers up to make mission control appear on the screen) is not working;

b) Exposé: (move fingers down to see apps working) is not working and so on (passing pages with two fingers and other gestures are not working).

I´ve opened the trackpad preferences and tried to configure it several times. It seems all to be right in the configuration pane.

Only one finger clicking to put the cursor in any place or click in a link; or two fingers clicking for contextual menus are working fine.

Moving two fingers to the left in order to see the notifications center also is working fine.

1.- I would like to know if somebody has the same problem (especially with mission control - moving for fingers up-; Exposé - moving four fingers down and passing pages or passing several desktops when working with more than one desktop - passing four fingers from right to left or viceversa).

2.- Also I would like if Apple knows about this and is working in an update to fix the problem.

3.- I would appreciate and be grateful if Apple or somebody could tell me haw to solve the problem, maybe in the case that I am doing something wrong or my claim has no sense.

Thank you very much in advance

P.S. I live in South America, so please I apologize for my terrible English.
