We are developing the iOS application which supports Universal Links and testing now.In the future, we will gradually update apple-app-site-association file to add paths.Does iOS fetch the apple-app-site-association files when the app is updated (not first install)?[Our investigation using Testflight]Version:iOS 9+Procedure:1. Upload the apple-app-site-association file to our server, and upload our iOS application (v1) to Testflight server(not AppStore).2. Download the iOS application(v1) from the Testflight server. ->iOS fetched apple-app-site-association file and Universal Links worked successfully.3. Upload the “new” apple-app-site-association file added paths to our server. and upload the our iOS application(v2) to TestFlight server.4. Update the iOS application(v2) from the Testflight server. -> iOS did not fetch apple-app-site-association file and Universal Links did not work for new added paths.
