Wow. I’d be ticked if they’d pushed mine that far back after advertising that you‘d have it within 3 weeks of ordering.I got the same set up as you but I ordered March 9th.
Originally it was supposed to arrive 3 weeks after I ordered, the end of March. My window is now May 9th - May 29th, but I've stopped checking everyday so I don't know if the delivery window has been moving.
