You must still be on a waitlist in order to use the app. Do you remember getting the waitlist #? I signed up last Sunday and initially received #7xx then email said 19xxx, then it said 130xxx. By midnight or so I was able to access the app and was active on it since then.
I did the same thing at 6AM Monday morning. All week the app’s done nothing except tell me that my account has been created successfully, and the number 164,038 is on the bottom.
