League que doesn't pop

It's been happening to me for a long time already, it simply doesn't show the button to accept or decline and I can't cancel q... But after a few league resets I see the accept button and when I come into champ select it's just a matter of time until it just freezes and I can't lock in/ban. Just got a loss in my gold promos for that I don't understand this. Does anyone know how to fix?
