My situation happened at 1:30 AM EST on Graveyard. Unfortunately, it seems cinema files don't save if we join late, even if it's 2 mins after a match has started.
Try asking others in that match to send you a cinema file of the round. Then you could send it to that PSN, OR you could ask them to send the file right to it.
