I've been trying to access the previous episodes but have not been able to all day since the event started. I just returned to the game at the beginning of heresy so I wasn't around for echoes or revenant. I am on PlayStation and everytime I try to access them it says requires episode purchase. What's going on? It's been almost 24 hours since the event started and still can't access anything. It's been a big let down. Was really looking forward to the access. Thank you.
