Mine went off at 10 seconds in, thought it was my broadband as it has been ropey all day. Switched to phone tethering and it has been OK since a refresh of the browser. Buffered only once since then, which is aa good as can be hoped with iFollow.
Mine froze immediately after KO. I logged out & logged in again and it was fine for the rest of the game. The commentary was even devoid of "shoutouts".
