“Customers Telegram” not working.

Hi dev, thank you for the great plugin.

The bot successfully sends messages to my Telegram group so it is configured correctly.

For the customer to receive Woocommerce order updates, this never works. I have added my nickname both with and without the “@” at the begining of the name and I have tested several times changing order statuses but the customer never gets the order status update message.
If the plugin is configured to send order status updated to admin’s Telegram group, then the bot sends the messages to the group but the customer never receives the message on his Telegram.

I can confirm that the customer’s username appears in the order details page so it is saving this information.

Any idea what’s wrong?

Thanks!
