I have a wait page because I want Player 1 to wait for Player 2's decision. I don't want participants to wait too long on the wait page, so I have  timeout_seconds = 10. But participants don't seem to advance after 10 seconds. I'm using the new format with Otree version 5.10.4. Here is my code 

class Wait_a2(WaitPage):
    form_model = 'player'
    template_name = 'main1/Wait_a2.html' 
    timeout_seconds = 10   
       
    @staticmethod
    def before_next_page(player, timeout_happened):
        if timeout_happened:
            player.group.timeout_a1 = 1
