Description

In 5.11 it seems that the following code has been removed from in pro > blocks.php > acf_prepare_blocks()

// Replace className with wpClassName if it's set. This enables support for blocks API v2 filters.
if ( isset( $block['wpClassName'] ) ) {
	$block['className'] = $block['wpClassName'];
	unset( $block['wpClassName'] );
}

We've seen this causing issues on a few sites. Looks like a breaking change that should have been mentioned in update and the documentation?
