Used to be good! Now cannot use!

Updated app no longer lets me sign in from my phone where app resides because owner device # on my account is a MyFi Portable WIFi unit. App used to save me so much time to use to check my account, bill info and make a payment in seconds! Now I cannot sign in since my Verizon account owner device is a WiFi unit & not a phone where the app resides, even though I added my phone from AT&T to the account.
