Xfinity app not letting me log in

So i am a new customer. I went to set up my modem and use the app, and i cant get in! 

I can log in online on any browser or using my phones safari or chrome. I know i am putting my information in correctly cause i can log in online every single time without issue. 

But when i navigate to the application to put in the same information, it starts to log me in ( i get my 2 factor code) but then loops back to the sign in screen every single time. If i press sign in again, it says you are already signed in as : and my username, and when i hit sign in again, it loops back to the main screen where i have to press sign in. 

Ive tried using a friends app, and the same thing happens. I let them use my phone and they can get in without issue. 

Ive uninstalled the app more times than i can count. 

Disabled cookies in my settings, and re-enabled them 

Cleared cache and browser data on my device 

Reset my network. Just about everything but restore my device..

Ive been prompted to change my password more times than i care for, and I'm running out of passwords. 

I can confidently say that its not my issue.
