I had a minor problem, now solved, getting tix. Bought from seatgeek, then got a message from NU tix that, due to Ryan Field security, the tix would be fulfilled by them. Part of the message was that xyz was transferring the tix to me. So I set up an account, transferred the tix, but there were then none in my account. cat tix was responsive 2 times and resolved it by sending me a separate link to the tix, but it is hardly as seamless as a normal 3rd party purchase.
