I've been with TPG forever but in the last 5 days i have lost my internet twice for a number of hours.   I downloaded the TPG app as I believe it has a test your internet option.  The problem is i cannot connect with the app.  I have tried to use my normal TPG  account user name and password but i get  "login failed" , "The TPG  Username or password you have entered is incorrect".  I used my community credentials  and was told the same.   Then I said i had forgotten the password and asked for a temperoray new one.  It was sent to my hotmail account .  But it also gets the same error.  How can i log into the TPG app. Is it the same credentials as when I log into my account with TPG.  If so then I  know i am typing in the correct credentials because i can get in via the web site using the same username and password.    any ideas ?
