Suddenly, the app is completely unusable. Its telling me to login to my ho account, and when I am doing that, it just loads indefinitely saying that its taking time to redirect me to ho smart, so there is a link to click to get back to hp smart manully. And when I click that, hp smart just says, something gone wrong, and I am back to square one. Just a few days before, everything was fine. Suddenly, not sure what is happening. HP, get your act together and fix the issue ASAP.
