For those still waiting - trust the process! I know individuals in R1 where it took them 2 weeks to be matched.
Also unless it’s in-person on-campus, I disagree with MBAB that you get "available dates".
THis is from when I was matched when an interviewer in R1. "While you have both been notified of the match, the expectation is that you will contact your interviewer within three business days and work together to set up a date and time for your interview using the contact information below."
You are responsible to reach out and schedule. Same thing happened to my friend who had an in-person interview (not on campus).
