Few days ? we don't usually get livestream rewards for a release or two later. I still haven't gotten my physical R55 reward, as an example.
I think the OP meant the prizes given away randomly during Livestream, not the telethon stretch goals.
Greetings @Anticules. The prize drawings during the Livestream usually are delivered by the next day. Check the Claim Rewards in your Bank screen and see. One of my friends got a prize and it was there when she checked it this morning.
