My friend and I have been watching a stream of Siege for 13 hours and we still have not gotten one. I left it on over night and woke up to not finding a pack on my PlayStation version of Siege. We have logged in and everything to get the Esports packs from twitch.
Hey guys, thanks for reaching out and I am sorry to hear about the problem each one of you are having.
As it stands, if you did not receive any Twitch notification despite watching for reward qualifying period of time, this will be caused by either:
1. Not fully completing Twitch Drop registration process
2. Not viewing the event for qualifying time
For more information about how it works, have a look at the following article and Twitch Drops Information.
