About second or two after clicking the confirmation button on the Smart Match page, it reverts to unconfirmed state.
I had that problem before but usually I only need to make one page reload and it worked after that. Sometime it worked after restarting the browser. Unfortunately for last week or two it do not work at all at two different browsers on two different computers regardless of the page reloads or browser restarts. Clearing cookies didn't help either. Is there any way to fix that behaviour?
