This package unfortunately is not functional at all. Not even "easy" to configure, as you wrote and reported in your details.
Honestly? I would definitely and without a shadow of a doubt like to be reimbursed. It's definitely a huge rip-off.

Hi! We designed the app to be easy to set up, even if you're not a developer. However, we're always open to improving our documentation and making the app even easier to setup. Could you let me know what you found difficult to use? I'd love to help you overcome any challenges you've had and help you release your app :)
