Completed twitch drop and confirmed claimed, on the evening of the 14th it’s the 16th and I still haven’t got it
Same here…had the same issue with the Blazing Hippogryph and it never showed up even though its “claimed” on my Twitch account.
Did you make sure your account is still connected and logged in? I was able to claim it and it appeared instantly on my WOW account.
Yes i am logged in and connected to my Warcraft account
still haven’t gotten mine either. they’ve probably got a lot of drops to administer so its taking them a lot longer than usual to go through them. hopefully it won’t be too much longer though.
I also haven’t gotten mine. Account is connected and everything. I watched/claimed almost as soon as the drop event went live, so it’s been like 3 days now.
if no one gets theirs a week from now, then i’d say something’s wrong…but hopefully people will start getting theirs soon.
shameless bump, but its been two weeks since i claimed the drop, and still nothing showed up. 
not sure what’s going on, but i’m starting to wonder if this is ever gonna show up in my collection now.
hoping its not mailed to me honestly, cause not having an active account means it’ll go unclaimed and eventually expire after 30 days.
edit: roughly 3 weeks since claiming the drop, and it still hasn’t shown up in my collection. guessing it was a farce, or they’re backlogged with millions of people to go through in claiming the mount…but even then, it shouldn’t have taken THIS long. only took a day or two for the Fel Drake and Blazing Hippogryph mounts, let alone the other stuff.
