Hello @rosalitoudtohan!
You can reach the actual order number with {{ order.number }} placeholder. This placeholder is included in ShopMagic Example plugin.
We created ShopMagic Example plugin for everyone who wants to add custom action/filter/event or placeholder, and it contains some examples. One of the (pre-written and ready to use!) examples is {{ order.number }}. It should retrieve the actual order number. Works great when you are using any plugin which is overwriting standard WooCommerce order numeration.
This placeholder will be available immediately when you install and activate ShopMagic Example plugin.
ShopMagic Example plugin can be downloaded from here – https://github.com/shopmagic/shopmagic-example.git, and you can read more about it here https://docs.shopmagic.app/article/510-shopmagic-example-plugin
