Single thank you page URL on Multisite

Hi there,

We are having tracking issues with our WP Multisite, which seem to be fixed when we revert to a standard Check out page. We are currently using custom Check out and Thank you pages, built with Elementor.

However, when we revert to a standard Check out page, we can’t control the Thank you page, and both our sites redirect to the same Thank you page URL on the root domain, ie .co/thank-you/ instead of .co/au/thank-you/.

Questions:
1. Is the single, root domain Thank you page URL an error on our end, or is this how all Multisites are setup?
2. If this is an error, how do we fix it?

Thank you for your help.
