Hello,
I am able to log in on my computer just fine, however when I attempt to "log in" on my phone to navigate to view my bill or look at my data usage, I get the message "In Valid Credentials" (not a typo, this is exactly what the app says).
I know my password is correct, because if I intentionally type an incorrect password it returns "The information you entered does not match the information we have on file." It is only when I type the correct information that it tells me the information is "In Valid"
