I've been a Koodo customer since the end of October, 2014, and have never had an issue using the Koodo Selfserve app until recently. I've been registered to use the app since my services began, but upon attempt to sign in the past few days, I've been unsuccessful. A message box appears that tells me that I have either an incorrect password, or username. I have re-entered both, still unsuccessful, yet I can access the full website without a hiccup. Any suggestions for what I am doing wrong? I value the use of checking my usage and paying my bill through my phone.
