I know I’m not alone in saying it was not clear it needed to be linked both ways (Twitch to Battle.Net, and then Battle.Net to Twitch). I had it linked from Twitch to Battle.Net before today, but didn’t link from Battle.Net to Twitch until just a little bit ago. Going on 7 hours with a drop claimed but no access, and even after reading this thread, it’s still not clear to me if both needed to be active before the drop started or if I can still get it if only Twitch was active.
Regardless, I’ll be pretty upset if I can’t get the beta after signing up for it a month ago, Following the instructions of linking Twitch to Battle.Net (no instructions to do it vice versa) and then watching streams all day today.
