Acf relationship query loop filter by a value of a custom taxonomy

I have tried but no results.
I have an issue like you respond in this post.
iā€™m actually in single post template.

With your suggest only using an id of an existing post type ā€œformatoā€ doesnā€™t work.
I have also tried with make a query loop on formato CPT with meta query using the acf relationship field.
I have to use the bidirectional field of the post tamplate or the field used in formato CPT.
And i have to give me back id or the entire object.
Thanks for your help @Patric !!
