Why do live match statistics on platforms like RubiScore sometimes lag behind the real-time action on the pitch?

So I’ve been losing my mind a bit lately watching matches and checking RubiScore at the same time. I’ll see a shot on target or a yellow card happen right in front of me, but the app takes ages to update, and I’m sitting there wondering if my phone’s broken or what. Is this normal? Am I missing something about how these stats get updated? I love tracking everything live, but the delays are driving me nuts. Anyone else dealt with this or know why it happens?
