Apple wants users to upload a txt file at this path on the website for the new Apple Sign In registration.
For the newly announced "Sign in with Apple", we need to verify our domain that we're sending emails from with Apple. Their instructions: "All email addresses associated with your registered domains will be able to send and receive messages to and from customers using Apple’s private email relay service. To verify ownership of your domain, select Download to get the verification file, upload it at the URL listed below, and click Verify."
Wix site does not support txt file upload. So how do resolve this issue?
