It does take a long while to login and to go to another topic.
Then going to another topic speeds up, for a while.
Then it slows.
Clicking a function twice does not speed things up. Much like hitting the elevator button repeatedly, it is usually ineffective. The same when hitting the crosswalk button repeatedly. The function does eventually work, so patience is required.
Many of those crosswalk buttons do nothing to activate the walk signal, so I hear. It is for psychological comfort and potential signal activating if traffic management people want to set it up.
