Hi @tadeaskula
HPOS is a huge change in WooCommerce core and we ned some time to confirm that Disable Bloat plugin is compatible with this functionality.
After conducting some tests, the compatibility will be declared in the upcoming release. Please stay tuned.
You can also overrivde the check just now, by adding this code to your functions.php:
add_action('before_woocommerce_init', function() {
\Automattic\WooCommerce\Utilities\FeaturesUtil::allow_activating_plugins_with_incompatible_features();
\Automattic\WooCommerce\Utilities\FeaturesUtil::allow_enabling_features_with_incompatible_plugins();
});
The warning notices will still be displayed, but it will be possible to activate the plugins/enable the features from the respective UI pages.
