I've followed the documentation - https://developer.apple.com/documentation/sign_in_with_apple/sign_in_with_apple_js/configuring_your_webpage_for_sign_in_with_apple to setup the web popup version of Sign in with Apple. It is working up to the point that I complete the sign-in flow, but then the pop-up remains open on the success screen. No AppleIDSignInOnSuccess events are caught by my event listener. When I manually close the sign-in popup, a AppleIDSignInOnFailure event fires (see attached). I'm thinking this has something to do with me trying to get this to work from within my local development environment, since Apple doesn't allow a localhost port or an IP address to be assinged as the redirectURI for the service... The host specified in appleid-signin-redirect-uri must include a domain name. It can’t be an IP address or localhost. If that is my problem, then how am I supposed to develop and test the addition of this feature from within my local dev environment? Any guidance would be much appreciated.

When I click on my in-app subscription to edit the values, the page breaks and shows loading indefinitely. None of the info populates and I can't edit anything. I've tried clearing caches/data, changing browsers. The console error appears to reference a few JS errors: javascript "TypeError: Cannot read property 'value' of undefined at n.$scope.setupPageData (https://appstoreconnect.apple.com/itc/js/ng-app/controllers/app/iap_details_withIP_cntrl.3459d16bc3.js:230:50) at https://appstoreconnect.apple.com/itc/js/ng-app/controllers/app/iap_details_withIP_cntrl.3459d16bc3.js:3876:28 at n.$digest (https://appstoreconnect.apple.com/itc/js/compiled/lib/vendor.16d4284eeb.js:1:409859) at n.$apply (https://appstoreconnect.apple.com/itc/js/compiled/lib/vendor.16d4284eeb.js:1:411308) at i (https://appstoreconnect.apple.com/itc/js/compiled/lib/vendor.16d4284eeb.js:1:386680) at u (https://appstoreconnect.apple.com/itc/js/compiled/lib/vendor.16d4284eeb.js:1:388893) at XMLHttpRequest.y.onload (https://appstoreconnect.apple.com/itc/js/compiled/lib/vendor.16d4284eeb.js:1:389368)" javascript "TypeError: Cannot read property 'length' of undefined at $scope.refreshIAPDetails (https://appstoreconnect.apple.com/itc/js/ng-app/controllers/app/iap_details_withIP_cntrl.3459d16bc3.js:3245:48) at n.$digest (https://appstoreconnect.apple.com/itc/js/compiled/lib/vendor.16d4284eeb.js:1:409696) at n.$apply (https://appstoreconnect.apple.com/itc/js/compiled/lib/vendor.16d4284eeb.js:1:411308) at i (https://appstoreconnect.apple.com/itc/js/compiled/lib/vendor.16d4284eeb.js:1:386680) at u (https://appstoreconnect.apple.com/itc/js/compiled/lib/vendor.16d4284eeb.js:1:388893) at XMLHttpRequest.y.onload (https://appstoreconnect.apple.com/itc/js/compiled/lib/vendor.16d4284eeb.js:1:389368)" Not sure how to contact App Store Connect support to get help with this. It's been broken for quite a while.
