I start a challenge and the challenge never starts. The HUD disappears and I can't access the pause menu or any of the in-game menus. I can still skate around but it looks like the game has put me into some sort of limbo world where there are no other players and I'm not doing a challenge. Just stuck in-between. The only way to fix it is to End Task and re-open the game. It happens constantly though, so that doesn't really fix anything anyway.
