Hello @kalin104,
Thank you for sharing the detailed information. Indeed, FluentBooking currently has limitations with popup elements, as it has not been implemented for use within pop-ups, which is why it is not functioning for you. It will also not work in Elementor popups.
I have already forwarded this issue to our development team for further investigation and potential inclusion in future updates. Hopefully, they will examine it closely soon.In the meantime, you can embed it on a page using a shortcode, which may work for you, or link the calendar’s landing page URL as a button link.
Please let me know if you have any further questions or if there’s anything else I can assist you with.
Best regards!
Ruman Ahmed.
