WooCommerce Orders “Note to Customer” No longer works

Hi all,

Not sure exactly where I can post this, but I’ve tried reaching out to Woocommerce for support but their turn around times are incredibly slow and I need to have this resolved or at least know where to start looking in which common areas.

On my customer orders, I have the pane on the right where all order’s transactions and notes are generated, I have the option to add a private note and also have an option to send “customer note” that gets appended to their existing order email and then sent.,

Now whenever I try to send a note to customer, it just get’s stuck – doesn’t error out or timeout or anything it just gets stuck in a loop waiting.

Any ideas on where I can look to even begin to troubleshoot this? It’s impacting my customer orders at the moment where I always send custom messages/emails post order.
