Hello @diegoversiani ,
It seems that this issue was not resolved in the latest 3.2.6 version.
PHP Fatal error: Uncaught TypeError: array_merge(): Argument #2 must be of type array, null given in /var/www/html/wp-content/plugins/fluid-checkout/inc/compat/plugins/compat-plugin-woocommerce-subscriptions.php:535
Stack trace:

get_packages_review_text_linesstill does not properly initialize return variable ($package_review_text_lines). It should be initialized before foreach block.
Received the same email from Stripe.
Plugin was updated to latest version (v8.5.1) yesterday.
Reconfigured the webhooks as asked, although not sure how the actual problem is related to webhooks. Don’t know if that helped or not.
