We wanted to try the app, but the experience has not been ideal. First, optimizing the theme, which should take 10-15 minutes as per the instructions, took over two hours and never finished. After that, the app simply stopped loading, giving a "refuse to connect" error. We emailed support, and they reached out offering to help. Unfortunately, we had already installed and set up another app.
