Hi @wireb – thanks for writing in and apologies for the delayed response.
To properly trigger a popup on a button, first, you must set a?Click Open trigger?to your popup. For more details, see this documentation:?‘Click Open’ Trigger Settings.?
?
?Once done with that, you will need to copy the popup’s CSS class that will look like this?popmake-123?under?All Popups > Popups > CSS classes?column.
?
?In case you have used the?Gutenberg editor?to make create the button then could you please?click the button?and under the?Advanced settings?section (from the right sidebar),?there is a field to enter?Additional CSS Class (https://share.getcloudapp.com/eDuLdrxe).
?
?You can also check this screen recording from my test site to make it more clear for you:?https://share.getcloudapp.com/YEuvneB6
?
?Could you please try that and let us know if that helps you??
