I'm having the same problem. App was working ok last week and now it's telling me "invalid username or password". Called technical support and they tried to help but nothing wrong.
I have confirmed that there are known issues affecting passwords with the app. This will be resolved in future updates. As a temporary resolution, the password can be set to the previous password and used.
I needed to retrieve the password for the app on my droid. I had to reset it. Now, my wife's iphone does not give the option to log in. I have deleted the app, I have deleted it from her cloud. I have rebooted the phone. How can I log her phone in?
Floating/pinning this topic for now, as this may become a frequently asked question until it has been resolved with an app update.
My App will not work. I don't even have the option to use an old password. The app has failed since the update and just says invalid username or password and stays on page without any other options. I tried resetting phone and uninstalling and reinstalling app. Any further solutions to date?
