Orbi App Won't Accept Admin or Other Passwords

Hi, 

We just switched from Xfinity back to Fios today. Our Orbi mesh router is connected to our Fios router. For some bizarre reason, even though I reset the Orbi router and unplugged, etc. and reinstalled the Orbi app on my iPhone, the app will not recognize the admin password (which is supposedly password). I also tried the factory  password that is printed on the router and that didn't work either. Can someone please help?
