Just got this from Apple today:
Dear ____,
Following the introduction of the EU Omnibus Directive (2019/2161), which is focused on consumer protection legislation, you may be subject to corresponding obligations in certain affected countries. If you sell books in the EU, whether you’re located there or not, this Directive affects you. As such, Apple now enables you to add a URL in iTunes Connect as a means to provide contact and other information as required by the Directive.
In accordance with the Directive, the URL you provide must link to a website that contains the following minimum requirements: valid contact information with a legal address, email address, and telephone number. Please specify the entire URL, including the protocol (for example,
https://support.example.com).
To enter your contact support URL:
Sign in to iTunes Connect.
Click Agreements, Tax, and Banking.
Select the Legal Entity tab, then click Add Link under Support URL. A window will appear with Legal Entity fields.
Enter your Support URL, then click the Add button on the bottom-right corner.
The URL will appear on each title’s product page in all territories where the law is in effect.
If you have any questions related to this new URL, contact us. Any legal questions should be discussed with your counsel.
Best regards,
The Apple Books Team
