I tried log in the app using the memorized password that I have been using for over 2 years but system said it was invalid. I tried to reset the password, but the system said that my email address that I have been receiving alerts on for 2 years did not exist. I tried to recreate the account but then the system said the email address already exists. So, the system is telling me that an account for that email both exist and does not exist.
You are not alone. My app refused to let me log in as well. A phone call to their support and a pw reset worked on the THIRD attempt ! Since so many have complained they must have had some sort of server error/ failure but do not seem to have acknowledged it.
