Hi guys

Can you please try the following:
1. Edit the file: forms/post.php: line 499 and change the function ‘allow_save_post to:

	/*
	*  allow_save_post
	*
	*  This function will return true if the post is allowed to be saved
	*
	*  @type	function
	*  @date	26/06/2016
	*  @since	5.3.8
	*
	*  @param	$post_id (int)
	*  @return	$post_id (int)
	*/
	
	function allow_save_post( $post ) {
		
		// vars
		$allow = true;
		$reject = array( 'auto-draft', 'revision', 'acf-field', 'acf-field-group' );
		$wp_preview = acf_maybe_get($_POST, 'wp-preview');
		
		
		// check post type
		if( in_array($post->post_type, $reject) ) $allow = false;
		
		
		// allow preview
		if( $post->post_type == 'revision' && $wp_preview == 'dopreview' ) $allow = true;
		
		
		// return
		return $allow;
		
	}

Please let me know if this solves the ‘Preview button ‘ not working issue
