Cannot login to Mint.com using old Windows 8.1 app, installed on to Windows 10.
I have successfully reversed a working copy of the Mint.com app using WSAppBak back into an installation package from my laptop, and side-loaded it to reinstall it back to my Windows 10 desktop. The desktop previously had a working copy, and my Mint.com settings acknowledge it as a previously approved device. The reinstalled app starts without any issues.
However, every time I enter my email and password, which I know to be correct, the app responds with "Login Failed."
I know the possibility of support is slim, because Mint.com no longer supports the Windows app. Still, any help is appreciated on why the login keeps failing.
