Cannot access Xfinity app - “Access Denied”

I am a new customer and just signed up with internet today. I’m attempting to log into the Xfinity app and am given a screen that says “access denied”. I also have tried the “find your xfinity ID” link and when I enter my address it says “we do not recognize the address”. I did create an account with Xfinity then bought my service through my apartment community’s updater app. I am assuming me having 2 profiles with the same email may be causing this issue. I need to ensure i can access the app before i move into my new apartment in order to setup internet.
