This is hugely frustrating. The documentation states that these should pull through and fallback to automatic behaviour, which you'd presume are those set in App Store Connect. Whilst the policy link works, the EULA link doesn't, no matter what combination of settings or code changes I make. Has anyone successfully added a terms link button that automatically pulls through the standard Apple EULA when clicking/tapping that button and opening he sheet view?

Same query here. I've tried everything I can think of to get the terms link to render content based on App Store Connect configuration. I can only get it working in local development in Xcode builds by passing a dedicated url to the supposedly custom terms link field, which, according to both common sense and official developer documentation, isn't necessary. I've set the policy link there, which works, but the terms link never renders the proper content, despite having opted into the standard EULA.
