Same here. Started doing everything twice and still no codes... This is another #fail playstation... I really hope we all get the codes one way or another and we didn't around in PS Home for nothing.
The PS+ and Music Unlimited voucher codes came up fine for me, but the PlayStation Mobile, Destiny, Killzone: Mercenary, and The Last Of Us voucher codes failed to download. I had every quest completed except the E3 Theater one, and hoped I could just visit the Quest Kiosk later to see if the codes would come up. Each time I go up to the board, my quest progress is completely wiped.
Same problem here, as is my quest progress being completely erased, which is really getting annoying because 90% of the time I've left the E3 booth today, it's been involuntary. I have every reward except for the hoverboard, which I am unable to get because I am unable to complete the Home E3 quest again before I'm disconnected from Home, and often PSN itself.
Just for the record both me and my wife are having this same problem. I figured I'd wait for a fix but it's taking far longer than expected so I'll just post here and find something else to do until Sony actually gets around to helping all of us.
Unfortunately, I think we may be waiting for awhile. Sony makes great consoles and electronics, but their customer relations are terrible. It took me over two years just to be able to access these forums because of an issue that Sony's forum support didn't even try to help me with until almost two year of weekly emails to them.
Got all the rewards! (Took three run throughs but oh well very easy!) Now just waiting for the Voucher codes!
Getting the rewards haven't been the issue for anyone, really. The problem is getting the codes to appear.
