We have Odoo sh and we are in v15.
Now we do have multiple websites in our database. We have sh and we have multiple brands in our company.
Our mother company has a website built in our Odoo sh and it's published and is live in its custom domain.
We have built a website for one of our brands in the same database and it has its own domain.
Now we have to point that particular brand website to its domain.
I think these details might help you understand where we are in this and give us some guidance to sort this out.
Thank you for your support.
