Hi there @BoncreationsZA!
Don here from Shopify.
We can help out by enabling this setting for your account as you are already aware of the ramifications of a change like this.
In order to do so, I will need to verify that you are the owner of this account via email.
I'll send out an email shortly, where you can just reply from the account owner email address to approve this change and we can get to work.
All the best!
