Thanks for the swift reply Ben. We initially selected “let expo handle it for you”, and have since gone into Apple Developer and added Associated Domains to the provisioning profile manually, as well as added "associatedDomains": ["applinks:plantjammer.app.link"] to app.json. We then used ran exp build:ios --release-channel test, downloaded the IPA, and tried to upload it via Application Loader (Version 3.7.1 (1047)). However, we are getting the following error:
ERROR ITMS-90163: "Invalid Code Signing Entitlements. The entitlements in your app bundle signature do not match the ones that are contained in the provisioning profile. The bundle contains a key that is not included in the provisioning profile: 'com.apple.developer.associated-domains' in 'Payload/ExpoKitApp.app/ExpoKitApp'."
This seems to indicate that Expo is not actually fetching the updated provisioning profile?
