On a Single Post Page of a CPT I use the Taxonomy Terms Block to display the Terms of one specific Taxonomy. Even though I selected a post for the preview that has a term selected for this taxonomy I get the message “Taxonomy Terms content not found”. When I view the same Post in the frontend the Term shows up as expected.
this issue solved itself. I don’t know what happened. I tried reloading, regenerating and everything but nothing worked. Now I checked again and it works as intended. So everything is fine!
