WANT THAT LABEL review for Smart Product Filter & Search

This app was working great until they decided to remove the smart filters without any notice! An email was sent yesterday (Sunday / non-working day), to upgrade the plan as we have apparently exceeded 100 products. Today, the plan was removed before we could even respond to their email. How insane. We are still paying for the plan, but no smart filter's are there?The removal of the smart filters has caused affected product views on our website. So disappointing!
