Doesnt update boarding info

Failure. Sent me walking all over Houston International Airport my gate changed from C-18 to E-19, the other side of the airport. No notifications, no change to boarding informations. Went to the gate and was like asked why my plane wasnt listed. Completely horrible! Dont provide information if its going to be inaccurate.
