UI Extension Block Not Displaying in Customizer

The block works correctly on the Thank You page, but it no longer appears in the Admin Panel Customizer, where it was previously visible.

  • Issue Description:
  • The UI extension block is configured to appear on the Thank You page. It displays correctly on the storefront’s Thank You page, so the functionality itself is intact.
  • However, the block no longer displays in the Customizer view within the Admin Panel as it did previously.

Hi Nova,

When did this start happening? Did you make any changes?
