@trenbania So if I’m understanding you correctly you are trying to retrieve field values in a block…from a block on a different page? If that is the case then I have no idea how to do that.
Normally when I use the relationship field its retrieving posts from a specific post type. On CPT’s I don’t use Gutenberg, I just create the acf fields that are assigned to the cpt, not a block. Then the code we were discussing would work. But my CPT’s are very standardized and don’t have the need for arbitrary content via blocks. I have never had to retrieve values in a block from another block on a different page.
You may be able to use get_post_meta() but since I have never tried that with ACF I’m not sure exactly how that will work, or if it will work at all. Here is a forum topic I found real quick that might help you. https://support.advancedcustomfields.com/forums/topic/want-to-use-get_post_meta-instead-of-get_field-for-array/ You might need to also do a check to see if the block exists using has_block() https://developer.wordpress.org/reference/functions/has_block/
Sorry couldn’t be more help man.
