Hello,
Thanks for reaching out! Hmm, can you please go to your Theme and see if the "App Embed" toggle is enabled for your "Buttonizer widget"? If not, enable it and click Save in the top right corner. Please see my screenshot below for reference.
To get to this area of your store, go to Online Store, choose Themes, Edit theme, and click the App embeds icon in the small sub-menu as you see in my screenshot.
Let me know if that helps!
Cheers,
Tony
