You can display the ACF File field via post meta block using the Post Grid Combo plugin. This article will help you to display the ACF File field via post meta block.
To begin, insert a “Post Meta” block.
Insert the ACF File Meta field key into the Meta Key Field. [Note. I am using the ACF Plugin to set a post meta value].
Now choose ACF File as the meta key type.
Here you will get some meta keys and values. Use one of them to display the meta value.
