Unable to update privacy policy link on published app

Hi all,

I got an email from Meta saying my app's privacy policy is no longer reachable (404 error). This was due to our app website changing and the privacy policy not being carried over. We have a new link for the privacy policy, but I cannot for the life of me figure out how to change the link on the Oculus Developer site.

The app is already published and released on the App Lab store. I tried creating a new App Metadata instance but it will not let me save it at all, citing that the submission has already been approved and cannot be modified. If this is the case, how do I change the App metadata to reflect the new URL for the privacy policy?

Meta says they will take my app down tomorrow (Nov 2) if the privacy policy is not updated. However, there is no way that I can see on how to do that. The instructions in the email point to non-existent buttons/links on the Developer site. I am using the website to update this, and not the developer desktop app.

I should also note that the new privacy policy link is temporary so our app is not deleted from the app store tomorrow. A more permanent link will be made in due time and updated yet again.
