Hello,
Thank you for providing feedback on the issue.
We understand that the problem persists, even with the latest update, and we appreciate your patience. Our development team has noted that the issue does not occur on our standard installations, making it challenging to diagnose without specific details from your environment.
However, since you mentioned that the issue started after version 4.1.9, we suspect it could be related to a filter that was introduced in subsequent versions. To help determine if this is the cause, we suggest adding the following filter to your site’s functions.php file:
remove_filter('woocommerce_enable_order_notes_field', '__return_false');
This filter was added in a particular scenario in recent updates, and it’s possible that it’s causing an unexpected conflict on your installation. Testing this might help resolve the issue temporarily.
That said, to accurately diagnose and fix the problem, we would still need more detailed information from your environment, which unfortunately, we can’t obtain through the forum. We strongly recommend that you contact our support team directly via our Support Form. This will allow us to securely gather the necessary details and, if needed, request access to your staging environment to troubleshoot further.
We’re committed to helping you resolve this issue, and reaching out to our support team will enable us to provide more targeted assistance.
Thank you for your cooperation, and we look forward to helping you find a solution.
Best regards,
