I'm using FDP with Astra pro, the backend works fine, form too. Even the "configure" button shows up. But Designer himself on the front end does not show up. I've already looked for many solutions, from reinstalling to reconfiguring everything and removing plugins. Of course I have added views to the product, but it doesn't do anything :/

shortcode [fpd] totally doesn't work.

Hello Maciej, If you have tried everything and FPD still doesn't work for you. Please submit a support ticket so that FPD technical team can look at your issue closely. Thanks
